The electrocaloric effect (ECE)-induced temperature change (ΔT) in (Ba, Sr)TiO3-based ferroelectrics under unipolar electric fields was analyzed from the separate contributions of the dielectric constant (ε) and remanent polarization (Pr) based on the Maxwell relation. Consideration of the contributions of both ε and Pr is particularly important in a unipolar electric field operation, such as on/off field switching used in device applications. Direct ΔT measurements were also performed based on the lock-in thermography technique to verify the accuracy of the ΔT intensity estimated by the indirect method. The indirect and direct ΔT values were largely consistent. The ΔT intensity near the peak temperature of ΔT was dominated by the Pr contribution; a large ∂Pr/∂T was necessary to increase the overall ΔT magnitude. In contrast, a large ∂ε/∂T was essential to expand the operating temperature range of ΔT at temperatures higher than the dielectric maximum temperature. Quantitative understanding of the contributions of both ε and Pr to ΔT in unipolar electric fields is expected to guide the search for materials with a superior ECE.

With the rapid advancement of information technology, there is a pressing need to develop ultracompact and energy-efficient thin-film-based electro-optic (EO) devices. A high EO coefficient in ferroelectric materials is crucial. However, substrate clamping can positively or negatively influence various physical properties, including the EO response of these films, thus complicating the development of next-generation thin-film-based devices. This study demonstrates that reversible dynamic domain motion, achieved through substrate clamping, significantly enhances the EO coefficient in epitaxial ferroelectric rhombohedral Pb(Zr, Ti)O3 thin films, where the (111) and (111¯) domains coexist with distinct optical axes. In principle, this approach can be applied to different film-substrate systems, thereby contributing to the advancement of sophisticated EO devices based on ferroelectrics.

Colossal Dielectric Constant of Nanocrystalline/Amorphous Homo-Composite BaTiO3 Films Deposited via Pulsed Laser Deposition Technique Reviewed

We report the pulsed laser deposition (PLD) of nanocrystalline/amorphous homo-composite BaTiO3 (BTO) films exhibiting an unprecedented combination of a colossal dielectric constant (εr) and extremely low dielectric loss (tan δ). By varying the substrate deposition temperature (Td) over a wide range (300–800 °C), we identified Td = 550 °C as the optimal temperature for growing BTO films with an εr as high as ~3060 and a tan δ as low as 0.04 (at 20 kHz). High-resolution transmission electron microscopy revealed that the PLD-BTO films consist of BTO nanocrystals (~20–30 nm size) embedded within an otherwise amorphous BTO matrix. The impressive dielectric behavior is attributed to the combination of highly crystallized small BTO nanograins, which amplify interfacial polarization, and the surrounding amorphous matrix, which effectively isolates the nanograins from charge carrier transport. Our findings could facilitate the development of next-generation integrated dielectric devices.

Polarization at the compositional interface in Nb-doped metastable TiO₂-SnO₂ solid solutions Reviewed

Abstract

Polarization architecture was incorporated into metastable Nb-doped TiO₂-SnO₂ to deliver electron accumulation at the localized TiO₂-SnO₂ compositionally fluctuating interface. Specimens were quenched from various holding temperatures to ambient temperatures in air to avoid bimodal decomposition into TiO₂ and SnO₂ endmembers. At the lowest sintering temperature of 1,400 °C, the mixed phase containing TiO₂- and SnO₂-rich compositions existed as an intermediate state to the single-phase solid solution. The phase boundary became more ambiguous with increasing sintering temperatures, and the compositional fluctuation size reduced to single nanometers at 1,500 °C. The permittivity due to the interfacial polarization, ε _interface, increased steadily with increasing sintering temperature. The larger ε _interface values at higher temperatures are attributed to the greater density of the compositionally fluctuating phase interface, which leads to greater electron accumulation at the energy barrier between the two semiconducting layers.

Polarization contributions to DC bias characteristics of nanograined BaTiO₃-based ceramics Reviewed

Abstract

The domain configuration contributions to the DC bias characteristics of nanograined BaTiO₃ were clarified. Domain boundaries became more ambiguous with decreasing grain size (g.s.), whereas domain patterns partially vanished because of the reduction in BT ferroelectricity, in the g.s. range <1 μm. Additionally, intergranular stress increased with decreasing g.s., resulting in crystal lattice hardening in the vicinity of the domain walls (DWs) and suppression of dipole fluctuations in the DWs. These domain structural variations with the domain size (d.s.) reduced permittivity in the absence of a DC electric field, resulting in improvements in permittivity depressions in an electric field (Δε). Magnesium substitution slightly decreased the d.s. The increase in DW density upon Mg loading implied defect pairs, ${ { \rm{Mg } } }_{ { \rm{Ti } } }^{"}$–${ { \rm{V } } }_{ { \rm{o } } }^{\bullet \bullet },$ which acted as new DW pinning centers, thereby subdividing the DWs. The Δε notably improved via Mg loading, because a defect pair effectively pins the DWs under the electric field.

<jats:p>Spinodal decomposition (SD) was incorporated into Nb-doped metastable TiO2–SnO2 to achieve giant interfacial polarization. The dielectric characteristics were analyzed using an equivalent circuit involving electron migration, where the SD bulk is given by the universal dielectric response relation. Both the Nb–TiO2 and the Nb–SnO2 layers showed semiconductive behaviors. With increasing SD treatment temperature, the SD volume fraction increased, as did cation interdiffusion at the SD interface, resulting in a large dielectric loss. The optimal SD temperature was determined as 1100 °C, where the Maxwell–Wagner capacitance showed a very high value of 44.6 μF corresponding to the permittivity at the lowest frequency exceeding 106. Such colossal polarization was considered due to an accumulation of trapped electrons at the Schottky barrier at SD layers with different conductivities.</jats:p>

<title>Abstract</title>
Electro-optic (EO) modulators for silicon photonics using CMOS-compatible materials and processes are in great demand. In this study, epitaxial (100)-undoped HfO₂ and Y-doped HfO₂ thin films were fabricated on Sn-doped In₂O₃/yttria-stabilized zirconia(100) substrates at room temperature via magnetron sputtering. EO measurement of the Y-HfO₂ film using modulation ellipsometry showed that the phase was changed by 180° after application of positive and negative poling biases, and the modulation amplitude increased linearly with increasing AC electric field, indicating a linear EO effect based on ferroelectricity. The observed results indicate that ferroelectric HfO₂-based films are viable candidates for CMOS-compatible EO devices.

Metal organic decomposition (MOD) using octylic acid salts was applied to synthesize a BaTiO<inf>3</inf>–LiCoO<inf>2</inf>(BT–LC) composite powder. The Ba and Ti octylates were utilized as metal precursors, in an attempt to synthesize homogeneous BT nanoparticles on the LC matrix. The BT–LC composite, having a phase-separated composite structure without any impurity phase, was successfully obtained by optimizing the MOD procedure. The composite prepared using octylate precursors exhibited a sharper distribution and better dispersibility of decorated BT particles. Additionally, the average particle size of the decorated BTs using metal octylate was reduced to 23.3 nm, compared to 44.4 nm from conventional processes using Ba acetate as well as Ti alkoxide as precursors. The composite cathode displayed better cell performance than its conventional counterpart; the discharge capacity of the metal octylate-derived specimen was 55.6 mAh/g at a 50C rate, corresponding to 173% of the capacity of the conventional specimen (32.2 mAh/g). The notable improvement in high rate capability obtained in this study, compared with the conventional route, was attributed to the higher density of the triple junction formed by the BT–LC–electrolyte interface.

<p>Sm-doped CeO₂ ceramics were prepared by conventional solid state method. The electrical conductivity of the samples was measured under conventional heating and 24 GHz millimeter-wave (MMW) heating, and the results were compared. During MMW heating, 5 mol% Sm-doped CeO₂ pellets with different thickness were used as susceptors, meanwhile Al₂O₃ fiber board was used as thermal insulator and its design varies by the number of open channels. The aforementioned susceptors and thermal insulators dependency of conductivity values during MMW heating were studied. Conductivity of samples under MMW heating was found to be higher than under conventional heating. Results showed that the different susceptor thickness and thermal insulator design could result in different conductivity values. These results were attributed to the phenomenon of heat dissipation from surface and the amount of direct radiation reached the sample. Specific susceptor thickness and specific insulator design which leads to highest conductivity were identified. By combining these two effects, the largest enhancement of conductivity of ceria based ceramics was obtained.</p>

The effect of Mg loading on the high-frequency tunable properties and dielectric loss of Ba<inf>0.8</inf>Sr<inf>0.2</inf>Ti<inf>1−</inf><inf>x</inf>Mg<inf>x</inf>O<inf>3</inf>(BSTM) ceramics was investigated. Variation in the lattice parameters and the 90° domain configuration with Mg loading indicated a decrease in the tetragonal distortion. Additionally, the 90° domain size decreased slightly with a low Mg loading, up to 0.1 mol %, resulting in a higher domain-wall density compared with the non-doped specimen. The 0.075 mol % Mg-loaded BSTM ceramic exhibited the highest tunability; this was attributed to the domain-size effect. The loss tangent (tan δ) roughly decreased with Mg loading, due to loaded oxygen vacancies. The maximum figure of merit value (FOM = tunability/tan δ) at 10 MHz was achieved for the 0.075 mol % Mg specimen, twice that of the non-doped specimen, due to an increase in the tunability and a decrease in the loss tangent with Mg loading.

We measured the microwave and millimeter-wave behaviors of ceramics and metal powders as a basis for developing microwave and millimeter-wave heating technology. In this study, nitride powders were subjected to microwave absorption measurements at elevated temperature. These measurements were performed using a system comprising a vector network analyzer, a circular wave-guide fixture, and a vacuum furnace. The sample’s microwave absorbency was evaluated by the change in reflection power from the sample in the circular wave-guide fixture under vacuum heating. Measurements were performed at approximately 24 GHz and at temperature up to approximately 1100°C. Boron nitride (BN) exhibited almost no absorption of microwaves up to 1100°C, similar to the results of a low-loss oxide powder such as alumina. Dichromium mononitride (Cr2N) powder exhibited a rather high absorption of microwaves at room temperature. During vacuum heating, absorbency of Cr2N started to decrease at 300°C, and became almost zero at temperature greater than 600°C, similar to the behavior of iron powder. This result indicated that roughly packed Cr2N powder absorbs microwave radiation; however, during vacuum heating, the compact body was sintered and the whole sample body became a reflector of microwaves. This change was irreversible, and the sample maintained its reflection behavior upon the cooling. When a mixed powder of Cr2N (20 mass%) and Al2O3 was heated under vacuum, the compact sample exhibited microwave absorption that increased with increasing temperature. This change was reversible upon cooling. These results indicated that the mixed powder did not become reflector of microwaves; Cr2N particles were not electrically connected each other because the Al2O3 particles kept the Cr2N particles separate during the vacuum heating process.

Language：Japanese Publisher：The Surface Finishing Society of Japan

The interfacial pH during Ni plating from the Watts bath was measured by using a rotating ring disk electrode system where the Sb-plated ring electrode acts as a pH sensor. It was clarified that a linear relationship exists between the electrode potential of the Sb-plated ring electrode and the pH in the range from 2.0 to 6.5 and was also clarified that the Sb-plated rotating ring electrode could be used as a pH sensor for the electroplating process in these pH ranges. The Ni-Al(OH)₃ composite film was electrodeposited by controlling current density under certain conditions, while the rise of interfacial pH during the plating process was estimated from the in situ pH measurement described above. The results of the SEM/EDX observations showed that minute particles, probably aluminum hydroxide, could be deposited with nickel from Al³⁺ contained in a non-turbid Watts bath under certain conditions determined by the interfacial pH measurement described herein.<br>

Language：English Publisher：The Ceramic Society of Japan

Naβ-alumina is a two-dimensional ionic conductor in which conducting planes of Na + ion are separated by insulating spinel block layers. For practical use, Naβ-alumina needs not only high ionic conductivity but also mechanical reliability. Therefore, we prepared preferentially oriented Naβ-alumina ceramics by hot pressing and evaluated the ionic conductivity and mechanical strength. The ionic conductivity perpendicular to the c-axis-oriented plane was five times higher than that parallel to c-axis. From the preferentially oriented Naβ-alumina ceramics three types of test pieces were cut for a three-point bending test. In one type of test piece, the longest side was parallel to the hot-pressing direction, while the longest sides were perpendicular to that direction in the other types of test pieces. The latter test pieces showed mechanical strength 1.5 times that of the former.

Effect of Moisture Absorption on Piezoresistance of Conducting Polymer Composite Thin Films

　More details

Language：English Publishing type：Research paper (scientific journal) Publisher：IOP Publishing

This paper is devoted to the study of the piezoresistance of conducting composite thin films consisting of epoxy resin and needle-like conductive fillers. The surface resistivity of the thin films at room temperature depended on filler volume fraction and relative humidity (rh). The effect of moisture absorption on the piezoresistance of the composite thin films was studied under various rh values. At high rh values, strain dependence of resistance was positive, and this positive coefficient decreased with decreasing rh value. At 30%rh, it became negative and its absolute value increased with decreasing rh. These results suggest that the piezoresistance effect of the conducting thin films is enhanced by moisture absorption by the epoxy matrix that is relatively hydrophilic. From these observations, the piezoresistance effect is considered to be based on the following two strains: one is derived from a mechanical stress and the other is due to environmental stress induced by moisture absorption.

Matrix-Dependent Percolation and Resistivity versus Temperature Behaviors of Conducting Composite Thin Films

Language：English Publishing type：Research paper (scientific journal) Publisher：IOP Publishing

The surface resistivity of crosslinked polymer matrix conductive ceramic filler composite thin films was studied as a function of composition and temperature. Epoxy resin and unsaturated polyester resin were selected as the insulating matrices. The resistivities of both thin films showed a percolative conduction, and the critical percolation threshold values of the filler weight fraction depended on the type of insulating polymer. The epoxy composite film exhibited a pronounced positive-temperature-coefficient-of-resistivity (PTCR) effect above the glass transition temperature of the matrix. In contrast, the unsaturated polyester composite did not show such an effect. To examine the nature of the percolation and the resistivity versus temperature behavior, the adhesive strength measurements and thermomechanical analysis were conducted on the matrix polymers. The results suggest that the percolation behavior and the occurrence of the PTCR effect in conductor-filled crosslinked polymer composites can be more precisely calculated by taking into account the thermomechanical interaction factor of the components.

Single crystals of (Ba_<0.96-x>Ln_xSr_<0.04>)TiO_3 (Ln=La, Gd) were grown over a composition range of x=0.001 to 0.03. Electrical resistivities of the single crystals were measured by the DC four-probe method. The temperature dependence of resistivities of these crystals changed from semiconductive to metallic at the Curie temperature (T_C). Although the room temperature resistivities of Gd-doped single crystals were independent of Gd concenration of 1 to 3%, they decreased monotonically with increasing the dopant concentration after annealing in a reducing atmosphere.

Mechanical Strengths of BaTiO3 Thick Films after Dielectric Breakdown

Journal of the Ceramic Society of Japan 96 ( 1116 ) 847 - 851 1988

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Ceramic Society of Japan

Mechanical strengths of porous BaTiO_3 thick films were measured after dielectric breakdown , the bending stress was applied to the position where the electric field had been applied. Comparison of the Weibull plots of mechanical strength between electrically failed and unfilled (as-sintered) specimens has shown that no damage due to dielectric breakdown occurred and that the poling process naturally involved in the dielectric strength measurement increased the mechanical strength. Mechanical strength before dielectric breakdown was estimated by taking into account this strengthening effect which depended on the poling voltage, time and temperature. A clear correlation between mechanical and dielectric strengths was obtained with the correlation coefficient of 0.73.

Language：English Publishing type：Research paper (scientific journal) Publisher：Ceramic Society of Japan

Mechanical and dielectric strength were measured for three types of BaTiO_3 thick films prepared under the different processing conditions. In any case, Weibull moduli for both strength distributions were identical in each type of films, though they differed among three types. The results indicated that dielectric strength measurement is a promising alternative method to distinguish the structural reliability change as influenced by processing parameters before firing within the framework of the same fabrication method .

RADIOISOTOPES 51 ( 2 ) 60 - 65 2002

　More details

Language：Japanese Publisher：Japan Radioisotope Association

Effect of plasticization on free-volume hole size observed by means of positronium lifetime measurement was studied. Glass transition temperature significantly decreased with an increase of dioxane content while free-volume hole size increased Temperature dependence of the excess free-volume hole size by addition of dioxane was examined Hole formation energy E^Ps_H for the excess free-volume was estimated on an assumption of a Boltzmann type distribution. As the result, estimated value of E^Ps_H well agreed with those for several polymer systems previously obtained by means of heat capacimetry.

The degree of enhancement of interdiffusion in the ceria-zirconia system increased as the Ce ion concentration increased, and showed a larger value under millimeter wave irradiation at any concentration. It is considered that this is because ceria absorbs millimeter waves more than zirconia, and thus the the driving force of diffusion depends on Ce ion concentration. Both the electric furnace and millimeter wave diffusion improved the Vickers hardness of the titania through the mutual diffusion contacted with tin oxide, but the flexural strength improved only by the millimeter wave diffusion annealing. It was possible to perform low temperature sintering by millimeter wave heating to ceria and zirconia with small substitution amount, which suggested cation migration promotion. It was also possible to suppress grain growth and bending deformation, suggesting related cation migration suppression

Aiming for an application to the high temperature pressure sensor, semiconductive ceramics foam incorporated with a narrow slit has been fabricated by the superplastically foaming method. We investigated the pressure dependence of resistance on the zinc oxide based foaming body, by changing the fabrication process and composition. The resistance of the sample decreased with an increase in pressure both at room and high temperatures. The performance of this type of sensor has been improved by doping ambivalent atoms (Ag and Li) into the matrix.

ミリ波焼結を用いAlNを中心とした窒化物を焼結することのメリットは、選択加熱によるエネルギー効率の向上と非熱効果による等温下での焼結の促進であり、後者も最終的には生産性の向上をもたらす。既に報告者は、24GHzジャイロトロン管を用いたミリ波焼結により、これまでAlNで報告されている内でもっとも低い1700℃で相対密度97%以上の緻密化に成功していた。本研究の第一の目的は、ミリ波焼結とHIP焼結を組み合わせて、トータルの処理時間を短縮してこれまでと同等の高い熱伝導率の試料を得ることにある。複合焼結法では、温度、時間、雰囲気の全ての点での優位性が示された。また、一次焼結を同一条件の常圧焼結したものと比較すると、ミリ波一次焼結試料の熱伝導率は50%以上高いことがわかり、ミリ波による一次焼結が有効であることがわかった。ミリ波一次焼結1600℃の試料の添加物依存性に着目すると、密度は添加量に従って増加するが、熱伝導率は逆になっていることが興味深い。複合焼結では添加物の最適値が従来焼結、単独焼結とは異なる可能性が示された。また、ミリ波照射が拡散におよぼす影響を調べるため、イットリア安定化ジルコニアを用いミリ波照射により昇温したとき得られる導電率を、電気炉により同じ温度にしたときの値と比較した。試料と周辺の温度を同一に保った場合、500℃でミリ波照射下の導電率は通常の電気炉昇温に比べ、2.4倍の値を示した。これによりミリ波照射による拡散促進が示唆された。また、導電率が最大となる最適構造が、通常加熱とミリ波加熱では異なる結果が得られた。

In this research, we have developed novel and highly accurate simulation methodologies for nanostructured materials that are used in ultra high-speed mass communication devices. We have applied the methods to clarify the effects of defects, grain boundaries, and impurities on electronic and magnetic properties of nanostructured ceramics and semiconductors.
During the research term, we have obtained the following outcomes:
1. The electronic transportation coefficient in Si nanowires has been calculated via the time-dependent Schrodinger equation based on the tight-binding approximation;
2. The diffusion processes of the impurity hydrogen in a Si crystal and grain boundary were analyzed by hybrid quantum/classics molecular dynamics method. We have found possible mechanism of the sudden drop of activation energy of H atom around and above 1000K due to the interactions between the defects and the impurity.
3. We have found the possibility that the residual magnetization of diamond is locally generated when Ni impurities were inserted at interstitial sites.
4. The spin polarizability in low-dimensional electron system was evaluated through the correlations between electrons trapped in low-dimensional system by the classics map method.
5. The structural and normal-mode analyses were performed to investigate the relationship between melting processes and the vibrational modes.
6. The finite-difference time-domain (FDTD) simulation methodologies for electromagnetic responses of meta-materials were developed and applied to the metal-insulator multilayer structures.
We have presented these results in a lot of domestic societies meetings and in four invited lectures.

セラミックス材料は、高温構造材料として用いられているが、粉砕によりリサイクルしようとすると強すぎる強度が問題となる。しかし、作製時に強度を低く抑えると、供用の際信頼性が問題になる。我々は、既にジルコニアセラミックスに圧電体であるチタン酸バリウムを分散させた複合体を作製し、分極の方向にで内部応力を制御することにより強化・劣化が随意に行えることを実証したが、現時点でプラスマイナス15%程度の強度制御しか行うことができていない。
同じ無機材料でもガラスでは、急冷やイオン交換により圧縮応力を残留させ、強度を大きくした、いわゆる強化ガラスが用いられている。融点が大きく作製時点で塑性流動の小さな多結晶材料では、急冷により亀裂が生成したり、密な構造中にイオンの出入りが困難であったりするため、これら物理的・化学的な手法での強度制御が行われていなかった。高強度セラミックスは強化ガラスの十倍以上の強度を有し、このような高い強度材、高融点の耐火物においても強度制御が望まれていた。
本研究では、ガラスより遙かに強度が大きく、高温でも軟化しないといった特性を有していながら、内部応力が熱緩和しないような低温でイオン伝導度、イオン交換能が大きなNaβアルミナセラミックスに着目した。ガラス同様にNaイオンをイオン交換することにより、50%にも上る強度制御が達成され、最高強度が500MPaと、構造材料として十分な特性を引き出すことに成功した。またこの材料は、強度値を熱処理により容易に低減できるというリサイクル性に優れた材料であることがわかった。更に、亀裂生成についても検討し、過剰なイオン交換は生成した内部応力によるマトリックス組織の破壊を導くため強度の劣化をもたらすことを見出した。すなわち強化には最適な交換量があることがわかった。

我々は既に高電圧印加により、機械的に弱い部材を抜き取る高電圧スクリーニング法を提案し、いくつかの系で実証している。本研究では、応力分布の異なる機械強度試験(三点曲げ、四点曲げ、二軸曲げ)を用い、その機械強度と絶縁破壊強度の相関について検討し、高電圧によるスクリーニングの試験方法依存性について知見を得た。
絶縁体試料としてチタニアセラミックスを用いた。市販粉末を一軸加圧により、直方体および円筒形に成型後、1400℃、3h焼成によりバルク試料を得た。ダイヤモンドカッターおよび手研磨により、4×12×0.3mm3およびφ=14mm,t=0.3mmの薄片試料を作製し、前者は三点曲げおよび四点曲げ試験に、後者は二軸曲げ試験に用いた。それぞれの場合について試料片を120枚作製し、半数でスクリーニング前の機械強度と絶縁強度の分布を測定し、30%の試料が絶縁破壊するスクリーニング電界を求めた。これを残りの試料に印加してスクリーニングを行い、絶縁破壊しなかった試料について機械強度分布を求め、スクリーニング前の分布と比較した。
スクリーニング前の機械強度の平均値は三点曲げ:188MPa、四点曲げ:128MPa、二軸曲げ:77MPaとなり、有効体積が大きくなるにつれ平均強度が減少することを確認した。スクリーニング前後の四点曲げ強度分布から、スクリーニングにより、低強度側が高強度よりにシフトし、強度分布が小さくなることがわかった。応力によるスクリーニング(保証試験)の理論線と比較すると、高電圧スクリーニングの結果はスクリーニング前と応力スクリーニングの中間に位置することがわかった。応力スクリーニングとの関係を三点曲げと四点曲げで比較すると、後者に対する高電圧スクリーニングがより応力スクリーニングに近いことがわかった。これは四点曲げの最大応力範囲が三点曲げに比べて大きく、高電圧スクリーニングの電界により近いためであると思われる。

This research aims to obtain high and reliable properties for NOx gas sensing and decomposition through controlling adsorption and decomposition behavior of NOx gas by applying electric field to conducting oxide ceramics. N-type conductive Nd_2CuO_4 ceramics showed a decrease of conductance by NO and an increase in conductance by NO_2 gas. Surface chemical binding states of NOX-adsorbates were analyzed with X-ray photoelectron spectroscopy, and different binding states for NO and NO_2 were confirmed for Nd_2CuO_4 and La_<2-x>Ba_xSrCu_2O_<6-delta>. In order to confirm effects of an external electric field on gas adsorption and reaction, changes in conductance by CO gas of SnO_2 thin film on SiO_2/Si substrate were examined under electric fields from the substrate. Acceleration of adsorption of positively-charged species like CO^+, and suppression of adsorption of negatively-charged species like O^- were confirmed under applying a minus bias from the substrate where apparent conductance of SnO_2 is lowered by the minus bias. Current changes of Nd_2CuO_4/stabilized zirconia/Pt element by NOx gas under a constant voltage (an negative bias to the oxide electrode) were examined. Even when two electrodes were exposed to a same atmosphere, increases in DC oxygen-ionic current by NOx gas, independent on ambient oxygen partial pressure, were observed. Changes in mixed potential by NOx and O_2 gases at the oxide electrode were found to be responsible for the enhancement of NOx decomposition and the NOx-sensitive DC ionic current. These results show that adsorption/desorption and decomposition of NOx gases could be controlled by using appropriate oxide material as an electrode and by applying an external bias.

We have proposed two methods to improve structural reliability of brittle materials. One of them is a simple evaluation of strength distribution using a simulations loading of many test pieces. The other is to establish a wise material with self-diagnosis function. Concerning the latter, concept, we have developed carbon-fiber-glass-fiber-reinforced plastic composite (CFGFRP), in which fatal fracture can be foreseen by monitoring the electrical resistance during and after straining. The resistance change of this composite is statistically interpreted using the fracture mode in a simultaneous loading system. The resistance change of the CFGFRP is found to be statistically reliable and reproductive.

Hardened gypsum and portland cement are chosen as a simple model of concrete and analogy beween the mechanical and dielectric strength distributions are found out. Both strength is evaluated in terms of Weibull statistics and the two-parameter Weibull function was adopted for both strength distribution. Both plots shows good coincidence independent of the water content during shaking of hemihydrate powder for hardening. At the hardened gypsum sheets which are made by shaking with 70wt% of water, both plots for mechanical and dielectric strength distribution show two straight lines with different slopes, however, both plots shows in good agreement. From the results, it is concluded that the mechanical strength distribution of hardened gypsum or Portland cement can be evaluated by using the dielectric strength distribution, which is casily obtained by breakdown testing.
The low frequency impedance of Portland cement paste or mortal increased with an increasc in curing time and it is strongly affected by the addition of NaCl. The contamination of NaCl would induce the alkaliaggregate reaction ane it induces a sudden fracture of concrete or mortal. When small amount of NaCl is added to cement paste with reactive aggregate (Pyrex glass), the impedance in anomalous increases after 3 days curing. After 365 days curing, the evidence of alkali aggregate reaction is found out at NaCl added mortal with reactive aggregate. By the continuous monitoring of impedance of mortal, the alkali aggregate reaction can be foresee and if the anomalous increase in impedance is observed in early times, the alkali aggregated reaction is apprehensive.
An alternative method to obtain a strength distribution of many test pieces at one time is proposed. In this method, bending stress of all subjected samples is simultaneously increased utilizing their elastic modules constancy and the fractured sample number is monitored by the change in electric conductance.

報告者らは、金属タングステンあるいは炭化タングステンに過酸化水素水水溶液を作用させると、新しいタイプの過酸化ポリタングステン酸が生成することを見いだした。この酸の水溶液から得られる非晶質薄膜は、深紫外線、電子線などの放射線に感応し、水系溶媒に対する溶解度が著しく変化するのでマイクロリソグラフィー用無機レジストとして興味がもたれる。また、本ポリ酸塩を前駆体とする低温焼成法により、応用上興味のある新規複合酸化物が得られることも前年度の研究によって明かになってきた。しかし、このポリ酸は非晶質としてしか固体化し得ないので単結晶X線構造解析が適用できず、ポリアニオンの詳細な構造は未確定であった。
本年度の研究では、非晶質X線回折によって提案された過酸化ポリタングステン酸のアニオン構造モデルを検証するために、赤外、ラマンの各分光法を用いた。その結果、調整当初の過酸化ポリタングステン酸は、WO^6八面体の稜共有による三員環と、同八面体の一カ所を過酸化物基により置き換えた五角両錘の頂点共有による六員環が結合してできたクラスターからなることがわかった。このクラスターの稜共有部分は熱処理により解裂し、頂点共有のみからなる構造となるが、この解裂は80℃を境に起こることがわかった。深紫外線を照射した、試料では、処理により温度はさほどあがっていないにも関わらず、稜共有部分は失われていることがわかった。また、縮重合に伴い酸素が放出されるが、その一部は固体中に捕獲されていることがラマン分校法により明かとなった。

(1).Development and Evaluation of New Electrochromic films
Peroxo-polymolybdotungstates are formed by the direct reaction of a mixture of metallic Mo and W (for example, 5 : 5 mixture) with hydrogen peroxide solution. A homogeneous and amorphous thin film (0.4 mum, typically) is fabricated on an ITO glass substrate by spin-coating using such a solution. After heat-treatment at 120 *, it exhibits electrochromism excellent in both reversibilty and response time in an organic Li-electrolyte.
The film colored at -1V (vs. Ag/AgCl) shows rather flat absorption spectrum. Its color is dark grayish blue and the DELTAOD between -1V and +0.5V reaches 0.7 at 670nm (lambda_<max>). Kinetic aspect of such electrochroic films will also be discussed.
(2).Coloration of electrochromic film in contact with polymer electrolyte
Electrochromic thin film of amorphous WO_3・nH_2O was fabricated by spin-coating a peroxo-polytungstate solytion. Coloration and bleaching kinetics of the film incontact with a solid polymer electrolyte were investigated by a chrono-amperometric method using a cell, Li/polymer/WO_3・nH_2O, ITO.The transition currents were analyzed on the basis of a newly proposed theory to be able to describe the diffusion-controlled current generated by a voltage step in such a cell without a reference electrode. It was found that both kinetics were controlled by the diffusion process and the chemical diffusion coefficients of Li were, in common, about 5 x 10^<-12> cm^2/s.
(3).Fabrication and evaluation of an electrochromic window prototype
A new thin film proton conductor based on tantalum oxide was developed from peroxo-tantalic acid. A prototype of electrochromic window in the tungsten oxide/Prussian blue system was fabricated using this conductor as an ion conducting layr. Successful and stable coloration-bleaching performance was demonstrated.

無添加のW-IPA薄膜について、加熱処理またはdeep-UV照射した試料についてラマン散乱スペクトル測定を行った。これらの処理により580および880cm^<-1>付近のピークが小さくなり、600〜700cm^<-1>のピークが大きくなる。このことより、ポリアニオンの網目構造が発達し重縮合が進むことがわかる。80℃で長時間保持したものについては100℃、0分処理のものと形状が異なり、むしろ80℃、0分のものと似通っている。このことから、80℃付近にある安定相が存在することが示唆され、これはIRでも確認された。またある程度の熱処理を施したものには、1550cm^<-1>付近にピークが存在し、生成した酸素分子はマクロな構造の緻密化によりケージングされていることが明らかになった。UV照射した試料のラマン散乱スペクトルは、100℃で熱処理した試料のものと類似していることがわかった。またこれにも同様に酸素がケージングされていることが明らかになった。これまでのX線動径分布関数を用いた解析によりW-IPAは、WO^6八面体の頂点共有と稜共有三員環からなるクラスター構造をとることがわかっている。以上の結果と合わせ熱処理またはdeep-UV照射すると、縮重合が進み不溶化し、同時に酸素がケージングされるものと考えられる。

報告者らは、金属タングステンと過酸化水素水の反応で生成する過酸化ポリタングステン酸のアンモニア塩を前駆体として用いることにより、六方晶三酸化タングステンが得られることを見いだした。これは、従来のWO_3・1/3H_2Oの熱分解によって生じる六方晶相とは明らかに異なるもので、三酸化タングステンの新しい準安定相と考えられる。これまでは現状は、少なからぬ不純物を含み、また、結晶性も十分ではないため、精密な構造解析は行われていなかった。この物質はアルカリ金属インターカレーションのホストとして興味深いが、このような機能も同じ理由により、系統的には評価されていなかった。本研究では、まず、前駆体アンモニウム塩の合成条ならびにその熱分解条件を精密に制御することにより、純粋で結晶性のより六方晶三酸化タングステン試料を得ることを目的とした。前駆体アンモニウム塩は過酸化ポリタングステン酸溶液にアンモニア水を加え、加熱後中和して析出させ、これを焼成して目的の物質を得た。純粋で結晶性のよい試料を得るため、前駆体中にパラタングステン酸アンモニウムの副生成しない条件および焼成時に高温相の生じない条件を検討した。さらにこの物質のX線回折により構造を決定し、従来の六方晶相との相違を明確にすることができた。第二に、この六方晶フレームワークがもつトンネル中、あるいはトンネル間プリズム位置への種々のアルカリイオンの電気化学的インターカレーションを試み、その可逆性やイオンの拡散挙動について検討した。この化合物を作用電極、アルカリ金属(本年度はリチウム)を対極および参照極とする有機電解液3電極セルをアルゴングローブボックス中で組立て、電量滴定的にインターカレーション反応を追跡し、その可逆性についても検討した。その結果充電時にはわずかな過電圧が見られるものの良好な可逆性を示した。

我々はこれまでに機能性電子材料セラミックスについて絶縁破壊と機械破壊の間に統計分布の相関を見いだしており、これら極致物性の相関を利用した機械強度の信頼性の代替評価法を提唱している。これまでBaTiO_3、TiO_2などを用いて様々な微細構造・表面状態の本代替評価法に及ぼす影響と適用性を明らかにしてきた。このセラミックスに対する新しい評価法^<1‐3)>は誘電体材料のかなりの離囲を網羅するものとして注目を集めつつあるが、その原理的裏付け・適用条件については十分な情報が得られているとは言えない。さらに、現在構造材料として広く使用されているセラミックスへの適用に関しては未知の部分が多い。
そこで本研究では、現在構造材料として広く一般に使用されているAl_2O_3を用いて構造材料セラミックスの本代替評価法の適用を試みると共に、この評価法の原理的裏付けに着いての考察、特に前年度熱衝撃の絶縁・機械両強度の相関を調べた際に、機械強度における折れ曲がり及び絶縁強度と機械強度の分布の相関の原因が熱衝撃によって生じたクラックであると報告したので、今年度はそのクラックと両強度の相関、特に予亀裂を導入することによって、その予亀裂と両破壊の起点との関係を明らかにすることを目的とした。
熱衝撃試験および予亀裂試験の結果、ヌ-プ圧子による圧痕のように亀裂先端の角度が極端に鈍い場合、その亀裂長さと方向が機械強度には大きく影響を及ぼすが、絶縁強度にはあまり寄与しない。また、クラックが表面傷先端から試料内部に進展している試料の絶縁強度は試料表面につけた電極がその内部のクラックをどの程度反映しているかに大きく依存すると考えられた。さらに、絶縁破壊試験により機械強度のばらつきを代替評価する際、弱点分布ひいては弱点そのものが等しく、また表面傷が少ないほど、その信頼性が高くなることを明らかにした。

An amorphous thin film can easily be fabricated by the spincoating technique using a solution of peroxo-polytungstic acid(WIPA), which is formed by the direct reaction of metallic tungsten with hydrogen peroxide. Amorphous W0_3・nH_20 given by heating such a film at 100-160ﾟC exhibits good and stable electrochromism similar to that of conventional evaporated WO_3 films. We examined the dynamics of coloration of those coated films on a newly developed analytical basis. The coloration dynamics was investigated by measuring the transition current when a sudden downward step of the potential was applied to a sample. The current didn't follow the Cottrell-type time dependency, which suggest the rate is noi controlled* by diffusion. The time dependency of current can. be explained by a Butler-Volmer type relationship, hence the dynamics was revealed to be controlled by the charge transfer step.
Tantalum and Niobium based amorphous solids were prepared. by drying respective peroxo polyacids. Alternating current electrical conductivity measurement's were carried out with pellet samples. Each specimen showed similar temperature dependency indicating its proton conductive mechanism was the same. The conductivity of Ta-IPA solid was larger than those of the others. Conduction mechanisms are discussed in relation to the water content and the structure of these materials.
Amorphous thin films Of MoO_3・nH_2O and (Mo, W) O_3・nH_2O are fabricated by the spin-coating technique from peroxopolymolybdate and peroxo-polytungstomolybdate solutions. Some fundamental electrochromic properties of these films were investigated in LiClO_4/propylenecarbonate solution. The colored films derived from MO-IPA exhibited stronger and flatter visible absorption spectra than tungsten-based film.

本年度は、実際に構造材料として用いられてれいるAl_2O_3を使用し、熱衝撃を加えた場合の絶縁・機械両強度分布の相関を調べた。
試料として三菱鉱業セメント(株)製アルミナフィルム(厚さ30μm.純度97%)を使用し、このフィルムを10mm+3.5mmに切り出した後、熱衝撃を加えた(△T=0K〜300K)。昇温速度は400℃/hで一定とし、所定の温度まで昇温、それぞれの温度で20min保持した後水中(20℃)に投下急冷することにより熱衝撃を加えた。
熱衝撃を加えていない試料の絶縁強度のワイブルプロットは良い直線性を示し、最弱リンク理論に則ったワイブル統計によって評価できることがわかった。さらに、絶縁・機械両強度のワイブルプロットはよい一致を示しており、絶縁体である構造材料セラミックスに対しても本代替評価法が適用できる可能性が示された。
熱衝撃を加えた場合には、200Kまでの熱衝撃に対しては両破壊とも平均強度値の変化はあまり見られず、200K以上の熱衝撃で徐々に強度が低下したが、臨界温度差△Tcを境にした急激な強度低下という現象は、本実験においては見られなかった。熱衝撃を加えた場合の絶縁・機械両強度分布を同一紙面上で比較したところ、200K以下の熱衝撃では両分布はよい一致を示した。250Kの熱衝撃を加えた試料では、機械強度の分布においてはっきりとした折れ曲がりが見られたが、絶縁強度の分布には折れ曲がりが見られず、両分布は一致しなかった。機械強度はクラックが曲げ方向に対して垂直か平行であるかによって強度が変化することから、折れ曲がりはこのクラックの方向を反映したものと考えると、表面亀裂などの弱点分布に異方性が存在する場合には、絶縁破壊試験においてはその異方性を捕らえることが出来ないために、代替評価法として使用する際には注意が必要であることも同時に示された。

現在、電子線露光により孔径0.1μm程度の微細パタ-ンを描き、これをマスクとして有機樹脂を微細加工することで高機能分離膜/センサ-膜の製作を試みている。一方、本レジスト材料は有機非線形材料(MBANP)と反応する事なく塗布することができるため、遠紫外線露光により線幅10μm程度のパタ-ンを描き、これをマスクとして下層の有機非線形材料を加工することも試みている。
過酸化ポリタングステン酸は単身で機能性を有するが、これを前駆体として用い、カルカリ金属、アルカリ土類金属と反応、生成した非晶質塩からは一次元あるいは三次元トンネルを有する酸化タングステン基骨格化合物が低温焼成により容易に得られることがわかった。本年度、塩を形成するカチオン種と生成する骨格構造との関係を調べた結果、生成する三種の骨格構造はカチオンのイオン半径と価数に関連付けられることがわかった。更にアンモニウム塩からは、これまで水熱法でしか得られなかった六方晶WO_3を合成することができた。この物質にK^+、Li^+の電気化学的インタ-カレ-ションを試みたところ、前者ではトンネル内のKサイト数に相当するまでの注入では骨格構造は変化せず、格子定数変化も小さいことがわかった。
MoについてもWと同様の方法により過酸化ポリ酸を調製し、そこから得られる固体相の構造と機能について予備的な検討を行なってきた。
Moを用いたときも過酸化基の存在量に対応した固体相が生成するが、Wを用いたときと同様金属原子と0_2^<2ー>の比が1対1の結晶相、過酸化基を含まない一水和物結晶相が得られた。両系ともに金属原子に対する過酸化基の比が1未満の非晶質相が得られるが、Moを用いた場合にのみ0_2^<2ー>の割合がMoに対し0.5の結晶相が生成した。得られた非晶質相は水に対する溶解度が高く、回転塗布による膜形成が可能であることがわかったのでその、EC特性・感光性について検討している。

タングステンに過酸化水素水を作用させると、新しいタイプの過酸化ポリ酸が生成する。この酸は種々のカチオンと不溶性の非晶質塩を作るが、これを前駆体として用いる低温焼成法により、通常の方法では得られない複合酸化物を合成できる。本研究は、このような方法で多くの複合酸化物母体(ホスト)を合成し、それらから導かれる導電性酸化物の物性を検討しつつ、超伝導体の探索を行なうことを目的として研究を行なった。
過酸化ポリタングステン酸(IPA)は、既報と同様に合成した。この溶液に硝酸バリウム攪拌しながら加えると、白色のバリウム塩(Ba-IPA)が沈澱した。この塩は、520℃で結晶化し、650〜700℃で別の結晶相に転移したあと、800℃付近でWO_3とBaWO_4に不均化する。通常の固相反応では800℃以上の高温を必要とするため、ここで得られた二つの結晶相を得ることはできない。
520℃で生成した最初の結晶相:xBaO・WO_3(=Ba_xW_<1-x/3>O_3,x=0.3)は、ほぼ正八面体のWO_6が頂点共有してできたフレ-ムワ-クを基本構造としている。この構造(空間群P6_3/mmc)は、既に報告のある六方晶WO_3や六方晶タングステンブロンズ(P6_3/mmc)とは異なる全く新しいものである。
ここで得られた化合物は完全酸化状態にあり導電性を示さない。導伝性を付与するためには何らかのド-ピングが必要である。Ba_xW_<1-x/3>O_3を例にとれば、Baを一旦プロトンにイオン交換し、これにLa^<3+>を注入するような方法が最も有望と考えられる。このためBa_xW_<1-x/3>O_3を1NHNO_3中で80℃加熱したところ、40%のBaが比較的速やかに交換し、母体の構造はそのまま保存されることがわかった。現在La^<3+>を注入する方法について検討している。xCs_2O・WO_3、xK_2O・WO_3も同様なド-ピングを行なう予定である。
