    <jats:title>Abstract</jats:title>
    <jats:p>Buried channel array transistors enable fast and high-density integrated devices. The depth of the PN junction and carrier dynamics at the depletion layer in silicon wafers have a crucial influence on their performance and reliability. Therefore, rapid and non-contact/non-destructive inspection tools are necessary to accelerate the semiconductor industry. Despite the great efforts in this field, realizing a technique to probe the junction depth and carrier dynamics at the PN junction inside wafers remains challenging. Herein, we propose a new approach to access PN junctions embedded in wafers using terahertz (THz) emission spectroscopy. THz emission measurements and simulations demonstrate that the amplitude and polarity of THz emissions reflect the junction depth and carrier dynamics at the PN junctions. It allows us to evaluate the junction depth non-destructively with nanometer-scale accuracy, surpassing the limits of traditional techniques. Laser-induced THz emission spectroscopy is a promising method for the sensitive and non-contact/non-destructive evaluation of Si wafers and will benefit the modern semiconductor industry.</jats:p>

    <jats:title>Abstract</jats:title><jats:p>In the field of millimeter-wave (MMW) imaging, the integration of artificial intelligence (AI) has emerged as a crucial solution for addressing automation challenges. In this study, concealed object classification was successfully achieved on point cloud data from MMW radar high-precision imaging using the PointNet +  + deep learning method. The utilized dataset comprises point cloud data generated through the transformation of 3D models and reconstruction of physical objects with an accuracy of less than 1 mm via MMW radar scanning. Classification accuracy was significantly improved by introducing data enhancement techniques, including the generation of homologous data and optimization of sampling points. After several evaluations, 300 epochs of training were conducted using 8192 sampling points, the results showed an accuracy of 0.998 for the training dataset and 0.996 for the test dataset. Moreover, evaluations of samples not included in the original dataset as well as multi-surface scans of concealed objects within the cardboard both resulted in correct predictions, which further validates the effectiveness and reliability of the study and demonstrates the potential of AI applied to MMW imaging.</jats:p>

    <jats:p>We present a novel technique for capillary electrophoresis (CE) using terahertz (THz) waves, namely “THz-CE,” which enables us to sensitively detect separated substances in a solution flowing in a hollow of capillary whose inner diameter is smaller than 100 µm. Such THz detection could be achieved by utilizing the near-field interaction between a solution filled in a capillary and a point THz source that was locally generated by optical rectification in a nonlinear optical crystal irradiated with a femtosecond pulse laser. Here, we investigated the performance of THz-CE numerically and experimentally, and succeeded in observing the electrophoretic chromatogram for the separation between acetic acid and <jats:italic>n</jats:italic>-propionic acid by THz-CE.</jats:p>

    <jats:title>Abstract</jats:title>
    <jats:p>Terahertz (THz) radiation encompasses a wide spectral range within the electromagnetic spectrum that extends from microwaves to the far infrared (100 GHz–∼30 THz). Within its frequency boundaries exist a broad variety of scientific disciplines that have presented, and continue to present, technical challenges to researchers. During the past 50 years, for instance, the demands of the scientific community have substantially evolved and with a need for advanced instrumentation to support radio astronomy, Earth observation, weather forecasting, security imaging, telecommunications, non-destructive device testing and much more. Furthermore, applications have required an emergence of technology from the laboratory environment to production-scale supply and in-the-field deployments ranging from harsh ground-based locations to deep space. In addressing these requirements, the research and development community has advanced related technology and bridged the transition between electronics and photonics that high frequency operation demands. The multidisciplinary nature of THz work was our stimulus for creating the 2017 THz Science and Technology Roadmap (Dhillon <jats:italic>et al</jats:italic> 2017 <jats:italic>J. Phys. D: Appl. Phys.</jats:italic>
    <jats:bold>50</jats:bold> 043001). As one might envisage, though, there remains much to explore both scientifically and technically and the field has continued to develop and expand rapidly. It is timely, therefore, to revise our previous roadmap and in this 2023 version we both provide an update on key developments in established technical areas that have important scientific and public benefit, and highlight new and emerging areas that show particular promise. The developments that we describe thus span from fundamental scientific research, such as THz astronomy and the emergent area of THz quantum optics, to highly applied and commercially and societally impactful subjects that include 6G THz communications, medical imaging, and climate monitoring and prediction. Our Roadmap vision draws upon the expertise and perspective of multiple international specialists that together provide an overview of past developments and the likely challenges facing the field of THz science and technology in future decades. The document is written in a form that is accessible to policy makers who wish to gain an overview of the current state of the THz art, and for the non-specialist and curious who wish to understand available technology and challenges. A such, our experts deliver a ‘snapshot’ introduction to the current status of the field and provide suggestions for exciting future technical development directions. Ultimately, we intend the Roadmap to portray the advantages and benefits of the THz domain and to stimulate further exploration of the field in support of scientific research and commercial realisation.</jats:p>

    This study conducted laser-induced terahertz emission spectroscopy on a VO2/Si heterojunction. Consequently, rapid estimation of the local interface potential was realized and the work function of VO2 was obtained as 5.17–5.25 eV with increasing temperature from 320 to 380 K. Moreover, an obvious terahertz emission variation was observed across the metal–insulator phase transition of VO2, and the doping conditions of the Si substrate largely influenced the terahertz emission. These results imply a strong relationship between the terahertz emission amplitude and the interface electric field, which supports the rapid performance of terahertz emission spectroscopy in estimating the work function of VO2.

    Lenses/mirrors with fast data acquisition speeds and extended focal depths have practical importance in terahertz (THz) imaging systems. Thus, a high-speed 600 GHz-band THz imaging scanner system with enhanced focal depth is presented in this work. A polygon mirror with a 250 Hz scanning frequency and an integrated off-axis parabolic (OAP) mirror with an ~170 mm focal depth were employed for 2D imaging. The simulation and experimental results show that a spatial resolution of ~2 mm can be achieved as the imaging distance varies from ~85 to 255 mm. The proposed system was applied to image a hidden metal object as a potential security application, demonstrating that this system can image targets with an enhanced focal depth.

    Abstract

    We have proposed highly efficient microcavity second harmonic generation devices. In this work, we designed and fabricated an a-plane GaN vertical monolithic microcavity second harmonic generation device pumped with a femtosecond laser and obtained normalized wavelength conversion efficiency of 0.15% W−1. The efficiency was comparable to the theoretical estimations taking into account the time evolution of fundamental wave intensity in the microcavity, second harmonic generation and even sum frequency generation. This result indicates the possibility of realizing ultra-compact and ultra-efficient devices pumped with long-pulsed or continuous wave lasers, in which the effect of resonance enhancement is even more pronounced.

    Abstract

    Far-UV light sources have attracted much attention for human-safe viral inactivation and bacterial disinfection. Due to large optical nonlinearity and transparency to this wavelength region, AlN is a promising material for compact and low-cost far-UV second harmonic generation (SHG) devices. In this study, a transverse quasi-phase-matched AlN channel waveguide with vertical polarity inversion was designed and fabricated. From wavelength spectra and a pump power dependence of an SH intensity, far-UV SHG via the largest nonlinear optical tensor component d33 was successfully confirmed under ultrashort pulse laser excitation.

    Twisted nematic type THz polarization control devices using liquid crystal immersed membrane films were fabricated by using simple stacking process. First of all, we verify the liquid crystal alignment effect in various kinds of membrane films. From THz Time-Domain Spectroscopy measurements, apparent refractive index anisotropy was observed in liquid crystal immersed Polytetrafluoroethylene and Polyolefin membrane films. Furthermore, transmission properties of twisted nematic type THz device are in rough agreement with 4x4 matrix calculation data. We believe that primary characteristic of THz TN device can be obtained by optimizing the fabrication processes and measurement method.

    Inspection and failure analysis of large-scale integrated circuits (LSI) have become a critical issue, as there is an increasing demand for quality and reliability in LSIs. Recently, we have proposed a laser THz emission microscope (LTEM) for inspecting electrical failures in LSIs, which detects the THz emission from LSIs by scanning them with femtosecond laser pulses. We successfully obtained the THz emission image of MOSFETs without bias voltage. We also measured MOSFETs in which the connection lines from the electrodes to the p-n junctions were interrupted, and found that the polarity of the temporal waveform of the THz emission from the pn junction in damaged MOSFETs has the opposite sign compared to that in normal MOSFETs. This result indicates that the LTEM can be used for the inspection of MOSFETs without bias voltage, which is attractive for the testing of semiconductor devices during the manufacturing process.

    The $c$-axis transmission spectra of underdoped Bi2Sr2CaCu2O8+δ (BSCCO) and YBa2Cu3O7-δ (YBCO) thin films were measured in the frequency range from 0.1 to 1.5 THz to investigate the mechanism of terahertz (THz)-pulse emission from high-$T_{\text{C } }$ superconductors (HTSs). The transmission spectra showed different properties depending on both the kind and hole-doping level of HTS thin film. A relatively strong shielding effect was observed for THz waves below the characteristic frequency $f_{0}$, which almost corresponds to the cutoff frequency $f_{\text{c } }$ in the THz-wave radiation spectrum. The observed THz-pulse transmission and emission properties are explained by the intrinsic anisotropic characteristic peculiar to each HTS sample. Particularly, the magnitude of the superconducting order parameter that is induced in the insulating barrier layer between CuO2 double layers plays an important role in determining the cutoff frequency $f_{\text{c } }$.

    Terahertz (THz) technology is becoming increasingly important in both science and technology. THz timedomain spectroscopy (THz-TDS) and THz quantum cascade lasers (QCLs) provide a powerful tool to explore the nature of various kinds of materials for a low energy excitation and ultrafast dynamics; the THz imaging is expected to be applicable to security, factory testing and so on. Thus THz-TDS and QCLs have triggered the research field of THz-technology-based basic research and application research. In addition to those activities, the development of ultrafast devices and logic circuits in the fields of THz photonics and THz electronics has accelerated the growth of the THz research field such as THz wireless communication, THz network system, ultrafast ADCs and so on. This paper reviews the future prospect of such THz-technology-based research fields.

    Ultrashort elctromagnetic pulses with time width of -0.5 ps are emitted from high temperature superconducting films by exciting with femtosecond laser pulses. The Fourier spectrum of them extends from 0.1 to 3 THz. The characteristics of the radiation are described in detail including various properties of the radiation related to magnetic fields. Various possible applications of this phenomenon are proposed and demonstrated. We propose a new field of "superconducting optoelectronics", in which ultrafast optoelectronics and superconducting electronics are combined.

    We observed the temperature dependence of a femtosecond time-transient photoresponse in YBa2Cu3O7-δ thin films by detecting terahertz (THz) emission. Ultrashort electromagnetic pulses which are referred to as THz emission were generated by ultrafast supercurrent modulation with femtosecond laser pulse irradiation. The transient response is discussed in relation to the quasiparticle dynamics of the nonequilibrium superconductor.

  • Growth mechanism of manganese-doped zinc sulfide films obtained by hydrogen plasma sputtering and its application to a thin-film electroluminescent device.

    Language:English   Publisher:The Japan Society of Applied Physics  

    ZnS:Mn electroluminescent (EL) devices were fabricated by the technique of hydrogen plasma sputtering (HPS). ZnS films were grown by HPS followed by annealing at 500°C for 1 h in a vacuum. Greater brightness was obtained when the growth of ZnS:Mn film was performed at 30°C than at 200°C. From the results of scanning electron microscopy (SEM) and electron probe microanalysis (EPMA), it was found that the quality of ZnS:Mn film deposited at 200°C is poor due to the lack of sulfur atoms. The films grown at 30°C are sulfur-rich and have better crystallinity. Manganese concentration of the HPS film increases with decreasing sputtering pressure. The growth rate shows the similar tendency with decreasing the pressure, which is explained by the glow discharge theory.

    The oxygen content y was measured in the superconductive ceramic Er_1Ba_2Cu_3O_y quenched at several temperatures. In the quenching process at 950℃ the oxygen content went down from 6.85 to 6.24. The critical temperature where oxygen fugacity starts was a bout 500℃. The superconductive transition temperature was strongly affected by the oxygen content. In those results, no essential difference could be found between Er_1Ba_2Cu_3O_y and Y_1Ba_2Cu_3O_y systems.

    We report unique terahertz (THz) spectra obtained from 4-dimethylamino-N-methyl-4-stilbazolium tosylate (DAST) emitters via optical rectification with three different pump sources. Superior homogeneity of our crystals was also confirmed by the spatial profile of THz generation efficiency. We also measured THz emission from various organic nonlinear crystals.

    The terahertz region of electromagnetic wave spectrum is ranging from 0.1 to 10 THz. There have been various studies for terahertz wave applications such as broadband communications, non-destructive testing and medical imaging. For the next phase of terahertz wave application, high quality of terahertz optical elements will be important. Liquid crystal materials show relatively large refractive index anisotropy in terahertz region of the electromagnetic spectrum and they are strong candidates for functional quality terahertz optical elements. In this study, we discuss the diffraction properties of liquid crystal grating for terahertz wave polarization measurement.

    In recent years, narrowband terahertz (THz) radiation along with broadband terahertz has attracted great deal of attention in both fundamental and applied sciences. For many frequency specific applications, the tunability of both central frequency and bandwidth of the narrowband THz radiation is vital. In this paper, a narrow band high intense THz wave generation system that can be used for simultaneous measurement of waveform and pulse energy is demonstrated. This system can produce frequency and bandwidth tunable multi-cycle THz pulses by optical rectification of femtosecond laser pulses using periodically poled lithium niobate crystal (PPLN), shadow mask and phase mask. The central frequency can be tuned by varying period of the phase mask. The power of generated narrow band THz wave can be measured using a superconducting edge triggered bolometer.

    High-power terahertz time-domain spectroscopy (THz-TDS) was used to examine YBCO and NbN thin films when transmitted by intense single-cycle THz pulses. This allowed for an investigation of the nonlinear, time-resolved behavior of superconducting thin films in the presence of strong THz electric fields with the field strengths of tens of kV cm^<-1>. We also investigated the nonlinear effect of a superconducting metamaterial made from niobium nitride (NbN) at terahertz frequencies. As the variation of the incident intense terahertz field alters the intrinsic conductivity in the NbN, a consequent giant amplitude modulation is observed due to the strong nonlinearities. The high sensitivity of the chosen metamaterial even allows observing the nonlinear behaviors at various temperatures, but the resonance modulation induced by the nonlinear effect was distinct from that induced by the heating effect.

    <p>THz electromagnetic wave has some unique properties such as penetration through various materials (paper, plastic, cloth etc.) and specific absorption band appears depending on materials (finger-print spectrum). There have been various studies for THz applications such as broadband communications, non-destructive testing and medical imaging. For the next phase of THz application, high quality of THz elements will be important. LC materials show relatively large refractive index anisotropy in THz region and they can have a potential application to some tunable devices. In this study, we investigate the reflective LC devices by using optically pumped submillimeter laser.</p>

    During the last decades, narrowband terahertz (THz) radiation has attracted great interests in both fundamental and applied sciences. For many applications, the tunability of both central frequency and bandwidth of the narrowband THz radiation are required. In this paper, a simple scheme to generate high energy, frequency and bandwidth tunable multi-cycle THz pulses by optical rectification of femtosecond laser pulses in periodically poled lithium niobate (PPLN) crystal is proposed and demonstrated. The central frequency can be tuned by varying the incident angle between the pump beam and the domain walls of a periodically poled lithium niobate crystal. The opportunity of easily tuning the bandwidth of THz generation from about 20 GHz to a few THz exists by changing the pump spot size on PPLN crystal, and the energy spectral density of narrowband THz generation is almost independent of the bandwidth.

    arious proposals using THz Time-Domain Spectroscopy (THz-TDS) have been performed in the semiconductor research field. Laser Terahertz Emission Microscopy (LTEM) acquires an image of the THz emission on a sample by scanning it with femtosecond laser pulses. The distribution of local photoexcited current can be visualized. We report on the results of the detection of THz waves generated from the multicrystalline silicon solar cell excited by femtosecond laser pulses and imaging the amplitude of THz waves, which reflect the instantaneous and local electric power generation. Moreover, we observed the decrease of intensity of THz radiation by CW laser illumination.

    Metamaterials that reveal fascinating and unique resonant properties allow for adequate control of electromagnetic waves at will. Recently, considerable studies have shown that plasmon induced transparency (PIT) effect can be realized by metamaterials via destructive interference between different resonance modes. Within the sharp transparency window, the high dispersion of the medium may lead to remarkable slow light phenomena and enhanced nonlinear effect. Here, we summarize research on terahertz PIT effect with various functionalities.

    THz electromagnetic wave has some unique properties such as penetration through various materials (paper, plastic, cloth etc.) and specific absorption band appears depending on materials (finger-print spectrum). There have been various studies for THz applications such as broadband communications, non-destructive testing and medical imaging. For the next phase of THz application, high quality of THz elements will be important. LC materials show relatively large refractive index anisotropy in THz region and they can have a potential application to some tunable devices. In this study, we investigate the new design scheme which includes the influence of absorption anisotropy in the THz LC components by using optically pumped submillimeter laser.

    We have developed a pump-probe laser terahertz emission microscope (PP-LTEM) to evaluate ultrafast carrier dynamics in electronic materials. PP-LTEM utilizes the terahertz emission from a sample excited by femtosecond probe pulses being irradiated to the sample after pump pulse irradiation. Using this system, we can evaluate the local or two-dimensional dynamics of photo-excited carriers in the materials with a time resolution of several hundreds of femtoseconds and spatial-resolution of 〜1μm. In this study, we evaluated two-dimensional carrier dynamics in a dipole type photoconductive switch fabricated on LT-GaAs, and observed the time-variation of screening of the electric field applied to the electrodes of photoconductive switch by pump pulse excitation.

    As an evaluation of ultrafast carrier dynamics in electronic materials, a terahertz emission from materials has been proposed. In this study, we have constructed a new system combining a pump-probe technique utilizing a femtosecond pulse laser with a laser terahertz emission microscope (LTEM). The developed pump-probe laser scanning terahertz emission microscope (PP-LTEM) enables us to evaluate local carrier dynamics in materials, and images carrier distribution in a time resolution. We have measured a dipole antenna fabricated on InP in this system, and obtained terahertz emission images in a subpicosecond time-resolution.

    We measured a terahertz response of an aligned single-walled carbon nanotube (SWCN) thin film on a sapphire substrate. In the measurements, we used terahertz time domain spectroscopy (THz-TDS) with a DAST crystal, which is a nonlinear organic crystal, as an optical source. This system enable us to measure absorbance of a SWCN thin film from 0.5THz to about 5THz. The results showed that the film worked as a good polarizer with over 0.9 degree of polarization in 0.5THz to 3THz. However the absorption of the film increased around 4THz and it decreases the degree of polarization.

    We have grown new stilbazolium crystals DASC and BDAS-TP from methanol solution. By using a femtosecond laser at 1560nm, these crystals generate broadband terahertz waves comparable to well-known DAST. DASC shows higher transmission in terahertz region. BDAS-TP has a different absorption dip at 0.8THz. Here we discuss the optical properties of the new crystals.

    Ultrafast optical devices are strongly desired to process large-capacity data-traffic on expanding information networks. A superconductive electronic device with high Tc superconductor is an attractive candidate for an ultrafast signal processing with very low power consumption. We have discovered that the local superconducting current could be modulated by the illumination of femtosecond laser pulses. As a result, magnetic fluxes were generated around the laser spot. Such phenomena are not only interesting for fundamental physics concerning an optical excitation of quantized states but also important from a viewpoint of the development of ultrafast optical devices using magnetic fluxes. Recently, we have fabricated a novel superconducting photonic device based on a Josephson vortex flow transistor (JVFT) with an YBCO thin film, and investigated the optical properties of this type of device using an optical measurement system with a femtosecond laser. In this report, we introduce our approaches to realize the ultrafast optical devices and show the recent results of optical signal processing with JVFTs.

    We have fabricated Josephson Vortex Flow Transistors (JVFTs) with the Josephson junctions that were prepared using YBa_2Cu_3O_<7-δ> (YBCO) thin films grown on bi-crystal MgO(100) substrates. We measured the responses with the DC and AC current input to the control line that was inductively coupled to the array of the junctions. In AC measurements, we observed the high frequency responses of the JVFT to the input current of sine wave or square pulse wave. In the DC measurements, we observed the modulations of the critical current and the flow voltage. From the results, we estimated the parameters of the device, e. g. the mutual inductance and the self inductance, and calculated the upper of the operation frequency that the device potentially possessed these parameters. We also discuss the feasibility of higher frequency operation to embed it in single flux quantum (SFQ) logic circuit from the results of DC and AC responses.

    We have fabricated a generation and detection system of sub-terahertz electromagnetic waves utilizing a photomixing technique combined with a high-T_c Josephson junction The electromagnetic wave with a different-frequency of two laser diodes was radiated from horn antenna, and the frequency was monitored as a voltage interval of Shapiro steps that appear in the current-voltage characteristics of a YBCO Josephson junction. In this study, we succeeded to generate and detect sub-terahertz radiation in frequency range from 62.9 GHz to 142.2 GHz.

    As recent development of teraherz technology, controlling or tuning of teraherz wave have been much attracted. The ferroelectric thin film show the change in the value of dielectric constant with the applied voltage bias, therefore we choose ferroelectric thin film for modulating the THz wave by applying voltage bias to the interdigital electrodes fabricated on the thin film. THz waveforms after transmission through thin film before and after applying voltage bias to interdigital electrodes have been measured in time domain at room temperature. The intensity of the peak of the waveform increases by applying the bias voltage. Our experiment result demonstrates that these thin films can be used for future frequency agile THz devices.

    We have measured terahertz(THz) radiations from unimplanted and Fe-implanted In_<0.53>Ga_<0.47>As photoconductive antennas excited by the femtosecond laser pulse of 1.56 μm wavelength. The maximum amplitude of the radiation waveforms from both the unimplanted and implanted emitters are found to be proportional to the applied electric field up to 5 and 12.5 kV/cm, respectively. The shape of the normalized THz radiation waveform from both the emitters is also independent of the magnitude of the applied field. The amplitude of the radiated waveforms from these antennas deviates from linear behavior, and saturates with increase in the power of excitation pulse. Fe-implantation to the samples reduces the THz pulse width from 0.80 ps to 0.56 ps. We also have detected THz waves triggered with 1.56μm femtosecond optical pulses, owing to Fe implantation.

    We proposed and developed a laser THz emission microscope (LTEM) as a novel tool for inspecting electrical failures in semiconductor devices. LTEM provides an image reflecting the electric field distribution in LSI chip by scanning it with fs laser pulses. By comparing LTEM images of a normal chip and a damaged one, we observed the difference in the LTEM image near the damaged area. Here, we report the experimental result on non-biased MOSFETs embedded in a test element group. We found that the LTEM images of damaged samples changed from those of normal samples both under biased and non-bia...

    We have investigated the properties of terahertz (THz) radiation from underdoped YBa_2C_u3O_<7-d> (YBCO) thin films. The THz pulses from current-biased YBCO are radiated due to ultrafast supercurrent modulation induced by femtosecond optical illumination. It was observed that the peak amplitude of the THz pulses increases almost linearly with increasing bias current and excitation laser power in certain regions for all samples. The maximum radiation efficiency was obtained for the sample with T_c = 61.5 K. Furthermore, it was observed that the maximum frequency of the Fourier spectrum slightly shifts toward lower frequency regions with decreasing hole-doping level. We discuss the shift of the maximum frequency in relation to Josephson plasma resonance phenomenon.

    We review the study on terahertz (THz) beam generation from strongly correlated electron systems; Pr0.7Ca0.3MnO3(PCMO), Tl2Ba2CaCu2O8+&delta; (Tl2212), and Bi2Sr2CaCu2O8+&delta; (Bi2212) thin films. Remarkable difference in thier emission properties and those from semiconductors or YBa2Cu3O7-&delta; (YBCO) is observed. The ultrafast carrier dynamics in the optically excited YBCO thin films is also discussed on the basis of its THz emission properties. Furhtermore, we report new results on the THz time domain spectroscopic studies of PCMO, La0.7Ca0.3MnO3, Bi2212, and SrBi2Ta2O9 thin films.

    Previously we reported about the magnetic flux generation in YBCO superconductive loop by femtosecond pulsed laser irradiation. In present study, to investigate the possibility of the magnetic flux generation in superconducting strip line, and to find out the relation between the laser beam power profile and the distribution of the generated magnetic fluxes, magnetic flux generation was tried in a YBCO strip line of 400 μm in width. Central part of the strip line was patterned into the ordered array of holes with a diameter of 2μm at an interval of 4μm. Using this sample, several experimental condition were examined by changing the pulsed laser beam power and spot size. To image the magnetic flux distribution, we observe the terahertz radiation from the presistent supercurrent around the magnetic fluxes with use of a well established terahertz imaging system. As a result, it was found out that magnetic fluxes can be generated not only in a superconductive loop, but also in the strip line independently of the antidot arrays, and further found that the generated magnetic flux density and its distribution strongly depend on the power profile of femtosecond pulsed laser beam.

    We observed Terahertz (THz) radiation from several types of YBCO thin film antennas. Polarization of the THz beam is characterized using three sets of the wire-grid polarizers. The radiation pattern suggests that there co-exist the radiation directly coupled to the antenna teeth and the one due to the wave propagation along antenna edges.

    We studied the supercurrent distribution in antidot-formed YBCO thin film strips by means of terahertz radiation imaging excited with a femtosecond laser. Antidots with a diameter of 2 μm were fabricated by Ar ion milling at an interval of 4&sim;12 μm on 100-nm-thick and 120-nm-wide YBCO thin film strips. We observed the supercurrent distribution images in the strip at bias currents between 0 and 460 mA, under the magnetic field between 0.9 and 25 mT, or in the remanent state at various temperatures, and compared them with the distributions in the strip without the antidots. The results indicate that the supercurrent in the antidot-formed strips distributes broader near the edges than that in the strip without the antidots, the vortex penetration from the edges strongly depends on the interval, the temperature dependence of the distribution remarkably differs from that in the strip without the antidots, and so on.

    We observed terahertz radiation from high-Tc superconductors and explained its mechanism as an ultrafast supercurrent modulation. Comparison between simulations based on rate equations for superconductivity and observed terahertz radiation waveform revealed that an intrinsic recombination life time of optically excited quasiparticles is shorted than 300 femtosecond at low temperature and increases with increasing temperature at near the transition temperature.

    We observed THz radiation from a-axis oriented YBCO thin film for the first time. The radiation efficiency of electromagnetic pulses from a-axis oriented thin film is about one order magnitude larger than that from c-axis oriented thin film. It is shown that the transmission in a-axis oriented thin film is higher than that in c-axis oriented YBCO thin film by measuring millimeter wave transmittance for YBCO thin films using a Mach-Zender type interferometric spectrometer. we have deduced that the enhancement of radiation efficiency for THz radiation is due to the enhancement of transmittance for electromagnetic waves.

    THz radiation excited by irradiation of femtosecond laser pulses was greatly enhanced for a bow-tie antenna device compared to a dipole antenna device. The maximum radiation power emitted into free space was obtained obtained 0.5μW with combination of the bow-tie antenna and a MgO hyper hemispherical lens. THz pulses has a half width of half maximum 0.44ps and its spectrum extends above 3THz. It is revealed that the bow-tie antenna and MgO hyper-hemispherical lens are effective to enhance the radiation power.

    Intrinsic Josephson junction arrays were made of Bi_2Sr_2CaCu_2O_<8+x> single crystals with a planar type structure. The columnal structure were formed onto the crystal in the range from l0 to 100μm in diameter and from 0.5 to 1.2μm in depth, which correspond to the array with between 330 and 800 junctions. Multiple branches in I-V curves, Ic dependence on an applied magnetic field, and microwave irradiation effects indicates that the devices work as a Josephson junction array. The similar type of devices were fabricated using YBCO thin films, which shows an RSJ-like I-V characteristic.

    Terahertz(THz) electromagnetic pulse emission from YBCO films has been demonstrated for the first time by using an irradiation of femtosecond laser pulses. The THz pulse has a half width of half maxmum 0.6ps and its spectrum extends above 2THz. The emission intensity increases quadratically with increasing bias current and excitation laser power, which can be qualitatively explained by a two-fluid mode for a superconductor. It is also revealed that a bow-tie antenna is effective to enhance the radiation power.

    本研究の目的は、ナノカーボン材料や、半導体原子層薄膜などの低次元ナノ構造に起因する特異な励起子やバレー自由度を持つキャリアなどの素励起を媒介とした、局所場超短パルス光・THz波変換機構を明らかにし、その知見を基に新規な光・テラヘルツ機能の開拓を行うことである。これまでに、一方向に配向した半導体CNTを用いた光伝導アンテナの作製技術を確立し、キャリア励起によるTHz波放射を観測した。CNTはファンホーブ特異性(VHS)のため、通常の半導体とはことなる特異な状態密度をとる。このバンド構造は、カイラリティ(螺旋度)と呼ばれるCNTの巻き方で決まっており、価電子帯と伝導帯の対応するVHS状態間の電子励起によるシャープな光吸収が起こる。また、クーロン遮蔽効果が弱いために、電子と正孔が対状態にある励起子が室温においても非常に安定であることが知られており、励起子相互作用がその電気的および光学的特性を支配している。我々は純粋な半導体であるカイラリティが(6, 5)であるCNTを用いて、ダイポール型光伝導アンテナを作製した。この、光伝導アンテナに波長580nm付近(いわゆるE22と呼ばれるシャープな光吸収帯)のレーザーを照射し、初めて明瞭なTHz放射を観測することに成功した。さらにこの、THz放射強度および同時に流れる光電流の励起レーザー強度依存性を測定した、THz放射はほぼ線形な振る舞いだが、光電流は非線形な応答を示すことを見出した。これは、エキシトンの励起・乖離過程が直接関係していることを理論モデルで構築し、それによるシミュレーションで検討した。その結果、フェムト秒光パルスでE22レベルに励起されたエキシトンは、弱い外部電界で即座に乖離し、e1電子バンドに遷移することで、高速電子加速が可能となり、テラヘルツ波が放射されることを突き止めた。

    InGaN/InGaN heterostructures with thicknesses of 1.5, 2,4 and 3.0 nm in the InGaN layer were fabricated as an example of atomic layer heterostructures. The heterojunction was irradiated with a femtosecond laser, and the relationship between propagation and charge dynamics in the GaN was studied, where optical carrier injection in InGaN quantum wells resolves the distortion in the heterojunction surface stress and simultaneously generates terahertz acoustic phonon pulses. (Currently writing a paper.)
    We have also developed a new theoretical equations to describe the fast electron dynamics near the surface of a graphene/semiconductor by means of photo-excitation of the carrier injection at the junction surface.We also studied the photo excitation of the excitonsin carbon nanotubes,which are good candidates as a base material of the hot electron emitting junnctions, and reveal their ultrafast fast carrier dynamics.

    本研究では、テラヘルツ(THz)波による超高感度・微量検査のためのTHzバイオチップの提案と開発を行った。チップ材料として非線形光学結晶を利用し、フェムト秒光パルスの集光によって生じる局所THz波光源とマイクロ流路内溶液を直接相互作用させることでTHz波による微量分析を行うチップで、流路構造やメタアトム(メタマテリアルの基本素子)構造の最適化を行いながらその性能を評価した。その結果、このような局所THz波光源でメタアトムを励起すると、数個のメタアトムからでも十分な共振応答を得ることができることからコンパクトな構成にできる上、メタアトムの構造非対称性を利用することで実量100ピコリットル中の溶液の濃度を最大フェムトモルオーダーの感度で検出できていることが確認できた。これは、本システムがコンパクトかつディスポーザルなTHzチップとして利用できる可能性を示すものであり、将来的に極微量の血液検査などの医療応用に道を開くものである。また、THz波は水の吸収が強いことで知られているが、これによるTHz波信号強度減衰を低減させた反射THzシステムの開発も行った。この反射型THzシステムとチップと組み合わせることで溶液のみならずパラフィンに内包された生体組織の観察にも成功した。本結果から、生体組織片などの高分解能THz分光・イメージングによる評価にも応用でき、癌診断等に展開することが買うであると考えている。これらの成果は、これまで難しかったTHz波による生体関連試料の微量分析やコンパクトなチップ開発を可能とするものであり、THz新産業へのブレークスルーに繋がることが期待される。

    A frequency tunable, narrow band, high intense THz wave generation system has been develoed. This system can be used for simultaneous measurement of waveform and pulse energy, and can produce frequency and bandwidth tunable multi-cycle THz pulses by optical rectification of femtosecond laser pulses using binary phase mask and lithium niobate single crystal. The central frequency can be tuned by varying period of the phase mask. The power of generated narrow band THz wave can be measured using a superconducting edge triggered bolometer. Uncooled microbolometer-based THz imagers were characterized using that system.

    We demonstrate a new approach to visualize the distribution of molecular adsorbates on graphene using terahertz emission spectroscopy and imaging. We found that the waveforms of terahertz radiation from graphene-coated InP sensitively changed with the type of the atmospheric gas, the laser illumination time. The terahertz waveform change is explained through band structure modifications in the InP surface depletion layer due to the presence of localized electric dipoles induced by adsorbed oxygen. These results demonstrate that terahertz emission serves as a local probe for monitoring adsorption and desorption processes on graphene films and devices, suggesting a novel two-dimensional sensor for detecting local chemical reactions.

Furthermore, the increase ofε" in the gigahertz frequency region and the increase ofγTO1 below T_c imply the existence of polar nanoregions that have been observed in other ferroelectric materials with a perovskite structure and relaxor ferroelectrics.

    平成20年度は現在までに構築しているレーザーテラヘルツ放射顕微鏡(LTEM)のシステム高機能化をを計るとともに、これを使った半導体デバイスの評価を行った。またこの高機能化したシステムに関する特許の申請を行った。以下に研究結果の詳細を示す。
    前年度までに従来の試料ステージ移動型のLTEMにビームエクスパンダーおよび固浸レンズを組み込むことにより、波長780nmのフェムト秒レーザー光源を使って、空間分解能として1.2ミクロンを達成していた。また、高速イメージングのためにレーザー走査用のガルバノメータを組み込んだ透過タイプのレーザービーム走査型LTEMを構築し、500×500画素のテラヘルツ放射イメージ取得時間を10秒程度まで短縮することに成功していた(従来の試料ステージ移動型では1時間程度必要)。
    今年度は、このレーザービーム走査型LTEMを、様々な試料に適応可能な反射型に改良し、またレーザー光源については多くの半導体デバイスのベースとなるシリコンを透過可能な1058nmに変更。さらにビームエクスパンダーおよび固浸レンズを組み込んだシステムへと拡張した。
    このシステムにより、0.5ミクロンのライン&スペース構造を有するテラヘルツ放射素子を用いて実験を行った。その結果、レーザービームをライン間に照射したときに放射される周期的なテラヘルツ放射パターンが観測されており、よって空間分解能として1ミクロン以下を達成した。
    また、この新システムを用いて、半導体デバイスの一つであるオペアンプのテラヘルツ放射イメージの観測を行った。人為的に配線に断線箇所を作ったオペアンプと正常なものにおけるLTEMイメージにおいて、有意な差を観測した。このようなテラヘルツイメージの差はアンプに外部から何もバイアス電圧等を入力しない場合にも観測されており、このLTEMを使って半導体デバイスの故障評価を非破壊で高速に行える可能性を示している。

    これまで、ジョセフソン磁束量子フロートランジスタ(JVFT)にフェムト秒レーザーパルスを照射し、その光応答から高速演算素子としての可能性を検討してきた。前年度にはJVFTの応答速度速度を検証し、JFVTの応答時間が5ps以下であることを示した。今年度は、さらにレーザーパルス照射時における精密な電流一電圧特性の測定、ジョセフソン接合からのテラヘルツ放射を計測を行い、さらにジョセフソン電流をナノブリッジに変えて同様のパルス照射実験を行った。
    精密なI-V測定を行った結果、光照射下ではI-V曲線にはFiske stepに似た電流ステップが観測された。これらは交流ジョセフソン効果と光照射によって生成された磁束が高速にチャンネルをフローする際に共振することにより発生したと考えられる。このように、光照射による磁束のダイナミクスを制御可能であることを示した。これと同時に、光照射されたジョセフソン接合からのテラヘルツパルス電磁波の発生・検出を行い、これに成功した。得られた波形から、光照射時の電流変化時間を見積もり、これまでの光電圧計測の結果と一致することが確認できた。また、100nm程度のブリッジ幅を持つナノブリッジの光応答計測にも着手し、パルスレーザー照射による出力電圧の発生も確認できている。このような取り組みにより、超伝導体の長短パルス光に対する応答を包括的に理解する礎を築くことが出来たと考える。

    This project aims to develop a laser terahertz (THz) emission microscope (LTEM) and explore its applications. The principle uses the THz radiation excited from many electronic materials with an illumination of femtosecond laser. The research subjects examined here are 1) designing and manufacturing the prototype of LTEM, 2) the evaluation of its performance and improvement, and 3) applications to observe various electronic materials and devices.
    We developed a free space type and scanning fiber probe type LTEM with either reflection mode or transmission one. The performance has been evaluated by using mode made line and space specimen. The minimum resolution for the free space type and probe one is better than 2 μm and 1.5 μm, respectively.
    First, the LTEM has been applied to see ferroelectric domain in multiferroic BiFeO_3 (BFO) thin films. We discovered the THz emission effect from BFO for the first time, and successfully visualized the feroelectoric domain. Then we applied LTEM to image an operational amplifier while operating, and successfully visualized the only signal lines related to amplifying process in the device. Finally, we examined its application to LSI defect analysis. We success fully distinguished damaged MOSFET in the Test Element Group from undamaged. The results prove that LTEM is promising new type of microscope for device evaluation such as LSI as well as various electronic materials. One can expect that LTEM can be improved to be available for dynamic microscope.

    本研究では、申請者が見出した光磁束量子変換効果を用いて、フェムト秒光パルス信号による2次元光情報制御の可能性を探ることを目的とする。平成16年度は、昨年度構築した高温超伝導体中に存在する磁束量子を観測するための磁気光学顕微鏡を用いて、引き続き磁束量子を観測するとともに、CCD読み出しなど装置改良と、デバイスへの適用を行った。その結果、以下の成果を得た。
    1.構成のCCDを組み込み、ファラデー素子にはBi置換型希土類鉄ガーネットを用い、リアルタイムで高分解能に観測できる磁気光学顕微鏡を開発した。そのとき、空間分解能約1μm以下を得た。
    2.高温超電導体であるBi_2Sr_2CaCu_2O_<8+δ>薄膜における磁束の浸入の観測をした。そのとき、三角格子を構成する単一磁束量子の観測に成功した。
    3.単結晶とエピタキシャル薄膜との比較を行い、単結晶では、a軸方向に沿って並んだ磁束量列が観測されたが、エピタキシャル膜では観測されなかった。このことから、磁束粒子の配列には欠陥が大きく寄与していることが判明した。
    4.YBCO薄膜を用いて、磁束量子制御用リングデバイスを設計・試作した。
    5.上記リングデバイスにおいて、磁束量子の侵入を観測したが、単一磁束量子の観測にはいたらなかった。
    6.デバイス評価用にBi置換型希土類鉄ガーネットをスピンコート法により自作し、磁束量子観測に適用した。
    以上、光制御のデモンストレーションまでにはいたらなかったが、単一磁束量子観測システムを開発するなど、大きな成果が得られた。

    This project investigates ultrafast carrier dynamics in photon-microwave conversion materials, and develops a highly controllable and stable tunable oscillator and photon microwave converter based on new idea.
    We successfully observed THz radiation from several kinds of HTSs and Mn oxides. It was discovered that Josephson plasma emission can be optically-excited for TBCCO under weak magnetic field. The carrier dynamics was observed by time domain. THz spectroscopy. It was found that oxygen reduced HTS strongly enhances the THz emission intensity due to the decrease in THz reflection at the interface between superconductors and substrate.
    We also observed THz radiation and ultrafast photo-response of a-Ge. It was found that a-Ge has potential as a photomixing excitation material for the use of light source with 1.55μm wavelength.
    We developed a photon-microwave converter by fabricating the hybrid device of photo-mixer and HTS Josephson junction, and succeeded in the generation and detection of the microwaves extending up to 200 GHz. We demonstrated the high controllability and stability of the microwaves generated by using the fabricated devices. We proposed this photon-microwave converter as a potential system to detect accurate optical wavelength.
    We also proposed an optically-controlled-terahertz flux-flow transistor as an optical direct interface between optical communication signals and single flux quantum logic circuits. The preliminary device was fabricated and tested under optical excitation.

    今年度は、高温超伝導体を用いたチューナブルマイクロ波レゾネーターの設計および製作を精力的に行った。
    高性能な無線通信用マイクロ波フィルターは、既に実用化されており、現在は、周波数可変型レゾネーターの開発・研究が精力的に行われている。よって本研究においては高温超伝導体を用いたコプレーナー型マイクロ波レゾネーターの設計・作製および特性の計測を行った。この素子はフリップチップ構造をもち、伝送線とキャパシタのギャップ間隔や、キャパシタの誘電率などで、素子特性が大きく変化する。これらパラメータに対する、素子特性の変化を詳細に計算し、構造の最適化を行った。そして実際に、SrTiO_3単結晶をキャパシタに、コプレーナー伝送線にYBCO薄膜を用いたチューナブルレゾネーターを試作し、その特性をベクトルネットワークアナライザを用いて測定評価した。その結果5GHz付近で約2.5MHzの共振周波数変化を示すレゾネーターの作製に成功した。今後、キャパシター材料を(Ba,Sr)TiO_3などに変更し、薄膜化することにより、さらに大きなチューナビリティを持つ素子の作製を目指す予定である。
    また、後方散乱型テラヘルツ電磁波イメージング装置の開発を行った。
    これまで、高温超伝導体にフェムト秒パルスレーザーを照射すると、テラヘルツ領域の電磁波が放射されることが、知られている。この電磁波を検出することにより、超伝導電流の流れを可視化することが可能である。しかしこれまでは、超伝導薄膜およびその基板を透過してきた電磁波を検出する透過型のシステムであったため、膜厚の大きいものや電磁波を透過しない基板を用いた試料は測定することが出来なかった。これに対し、今回開発したシステムは、レーザーを薄膜表面へ照射し、レーザーが入射してきた方向へ放射される電磁波を検出する、後方散乱型システムであり、このシステムを用いて、実際に超伝導電流のイメージングが可能であることを示した。このことにより、バルク試料や基板の制限なく、テラヘルツイメージングが可能となった。
    これらの結果は国際学会で発表され、すでに数本の学術論文として出版済みあるいは近日中に出版予定である。

    This project investigates terahertz radiation from high-Tc superconductors (HTSs), ultrafast carrier dynamics in HSTs, optical vortex generation due to ultrafast optical supercurrent modulation, proposal and developments of new photonic devices and systems.
    We successfully observed THz radiation from YBCO, TBCCO, BSCCO, and Pr doped YBCO, and discovered optically-excited Josephson plasma emission from TBCCO under weak magnetic flied. The carrier dynamics was observed in time domain with a time resolution of 100 fs using pump and probe THz emission spectroscopy. It was found that Pr-doping into YBCO strongly enhances THz emission intensity, which is attributable to the decrease in THz reflection at the interface between superconductors and substrate. We discovered new effect in optical vortex generation, can to be explained by the conventional rule of superconductivity. The mechanism was explained by ultrafast optical supercurrent modulation. We proposed to apply this new effect to detect and process femtosecond optical signals, and demonstrated to detect a single shot femtosecond optical signal via otpcal vortec generation.
    As an application research we developed Laser-Terahertz Emission Microscope (LTEM) and observed supercurrent distribution ih high-Tc superconductors. It proven that the LTEM is a potential tool to observe supercurrent and vortices in HTSs as the noncontact, nondestructively and free-space evaluation system.
    We also developed photon microwave converter by fabricating photomixer and HTS Josephson junction hybrid device. We proposed this photon microwave converter as a potential system to detect accurate optical wavelength.
    We propose optically-controlled-terahertz flux-flow transistor as an optical direct interface between optical communication signals and single flux quantum logic circuits. The preliminary device was fabricated and tested under optical excitation.

    本研究の目的は、II-VI族化合物半導体の水素化解離過程に関する知見を得、良質薄膜成長への応用を計るものであり、当該年度に得られた研究実績は以下のとおりである。
    1.水素プラズマと半導体(Si,GaAs,ZnS,CdS)の反応過程を、プラズマ発光分析、プラズマ状態密度および電子温度測定により検討した。その結果、Siとの反応では、SiH_4等のガス状分子が形成され、その他でもAsH_4、H_2S等の生成物が確認された。Ga,Zn,Cdはガス状ではないものの、ZnH等の水素化生成物として通常の金属よりも低い温度で昇華していることが示唆される結果が得られた。このとき、データ収集および解折には本研究費のうち設備品として購入したコンピューターを用いた。
    2.水素プラズマを用いたスパッタリング法により(100)GaAs上(100)ZnS、(100)CdSのエピタキシャル成長が確認された。しかしながら、現状は多くの積層欠陥および不純物の析出などの問題を抱えており、化学量論比の保たれるよう化学反応ゾーンと成長過程と分離を計っている。
    3.できた薄膜の評価は結晶性のみなのが現状であった。そこで、移動度の非接触評価を試みた。非接触評価にはヘテロ接合を作製し、その量井戸におけるエッジプラズモン励起の観測により行う方法を提案した。今回、n型GaAs系量子井戸において移動度の非接触測定が可能である事を初めて明らかにした。
