強誘電体やその周辺の酸化物を中心に,「電気分極は電子状態をどう変えるのか」という問いに取り組んでいます。

強誘電体は,コンデンサーやアクチュエーターとして広く利用されているだけでなく,近年では不揮発性メモリやエネルギー貯蔵材料としても注目されています。一方で,電気分極が電子バンド構造や表面電子状態をどのように変調するのかについては,まだ十分に理解されていない点が残されています。

主に,放射光X線回折による結晶構造解析,光電子収量分光,光吸収・発光測定などを用いて,強誘電体および層状ペロブスカイト関連物質の構造と電子状態の関係を調べています。最近は典型的な強誘電体だけでなく,他の酸化物においてもイオン交換や水和によって生じる構造変化が,真空準位基準のバンド構造や表面電子状態に与える影響に注目しています。

電気分極を利用した電子状態制御の学理を深め,高速不揮発性メモリや次世代電子材料の開発につながる基礎研究を進めています。

    Abstract

    Low-reflectance black materials play an important role in optical and thermal devices. In this study, boron-doped carbon nanowalls (CNWs) with extremely low reflectance were successfully synthesized using an inexpensive and simple experimental arrangement. Analysis of the nanostructures and surface morphology of the CNWs revealed that boron-doped CNWs had a higher wall density and lower graphitization than undoped CNWs. We discuss the mechanism of light absorption in terms of stray light effects originating from the nanostructures and the improved electrical conductivity owing to carrier doping. Boron-doped CNWs are considered beneficial for the implementation of this ultra-black material.

    Silica coating is performed onto silver tree‐like fractal structures, which are self‐grown in a solution, through a wet process using tetraethyl orthosilicate. Surface‐enhanced Raman scattering (SERS) of para‐aminothiophenol (p‐ATP) is measured on the silver tree‐like fractal structures with/without silica layer at the excitation wavelength of 532 nm. p‐ATP is chemically transformed into dimercaptoazobenzene (DMAB) on the non‐coated silver tree‐like fractal structures, where DMAB peaks are clearly observed, during the SERS measurements. The DMAB peaks decrease/disappear on the silica‐coated ones although the p‐ATP peaks were observed. The results indicate that the chemical transformation is inhibited on the silica‐coated ones. The sensitivity is decreased by half compared to the non‐coated silver tree‐like fractal structures, where the lower detection limit is estimated to be ∽2×10‐5 mol/L for p‐ATP. The silica coating is advantageous for inhibiting chemical transformations of analytes, enabling identification/estimation of chemicals in unknown sample with SERS similarly to conventional Raman spectroscopy.

    Millimeter wave absorption exceeding 70 GHz has been performed in a Co-substituted Ca–La magnetoplumbite (M-type) ferrite. A polymerized complex method was used to increase the substitution of La and Co ions in the M-type ferrite. The increase in the magnetic anisotropy field combined with the remaining significant saturation magnetization results in good magnetic resonance absorption in the millimeter range of 70–100 GHz. Above 70 GHz, good millimeter wave absorption of more than −20 dB was achieved in 0.25 mm thickness plates of Ca0.46La0.54Fe11Co0.28O19-η and Ca0.42La0.58Fe11Co0.58O19-η. Highly Co-substituted Ca–La M-type ferrites may, thus, be promising candidates for magnetic absorption materials operating in frequencies of up to 100 GHz.

  • Direct measurement of electrocaloric effect based on multi-harmonic lock-in thermography Reviewed

    We report on a direct measurement method for electrocaloric effects, the heating/cooling upon application/removal of an electric field in dielectric materials, based on a lock-in thermography technique. By use of sinusoidal excitation and multi-harmonic detection, the actual temperature change can be measured by a single measurement in the frequency domain even when the electrocaloric effect shows a nonlinear response to the excitation field. We demonstrated the method by measuring the temperature dependence of the electric-field-induced temperature change in two Sr-doped BaTiO3 systems with different ferroelectric-paraelectric phase transition temperatures, where we introduce the procedure for extracting the pure electrocaloric contribution free from heat losses and Joule heating due to leakage currents. This method can be used irrespective of the type of dielectric material and enables simultaneous estimation of the polarization change and power dissipation during the application of an electric field, making it a convenient imaging measurement method for the electrocaloric effect.

    Single-walled carbon nanotube (SWCNT)/TiO2 hybrids were synthesized using 1,10-bis(decyloxy)decane-core PAMAM dendrimer as a molecular glue. Upon photoirradiation of a water dispersion of SWCNT/TiO2 hybrids with visible light (λ &gt; 422 nm), the hydrogen evolution reaction proceeded at a rate of 0.95 mmol/h·g in the presence of a sacrificial agent (1-benzyl-1,4-dihydronicotinamide, BNAH). External quantum yields (EQYs) of the hydrogen production reaction photosensitized by (6,5), (7,5), and (8,3) tubes were estimated to be 5.5%, 3.6%, and 2.2%, respectively, using monochromatic lights corresponding to their E22 absorptions (570 nm, 650 nm, and 680 nm). This order of EQYs (i.e., (6,5) &gt; (7,5) &gt; (8,3)SWCNTs) exhibited the dependence on the C2 energy level of SWCNT for EQY and proved the hot electron extraction pathway.

    This paper reports the structural and optical investigations of the structural colour of the weevil
    <italic>Lamprocyphus</italic>
    <italic>augustus</italic>
    . The photonic crystal structure within the weevil's scales was investigated using sequential focused ion-beam milling and scanning electron microscopy imaging. We carefully analysed the reconstructed three-dimensional structure to determine the unit cell of the photonic crystal. It was found that the cuticle network of the cubic unit cell perfectly matches the previously reported diamond-based network. However, different results were obtained for the crystal orientations of the small crystal domains that comprise the entire photonic crystal structure in the scales:
    <monospace>&lt;111&gt;</monospace>
    directions are highly preferred along the surface normal of the scale. This finding explains the fact that the scale is almost uniformly coloured despite the multi-domain structure. It is confirmed experimentally and theoretically that the wavelength range of the reflection band corresponds to the gap of the photonic band.

  • Iron vacancy effect on the magnetization of YbFe2O4 Reviewed

    We report the effect of iron vacancies on the magnetic property of spin and charge ordered system YbFe2O4 single crystals. The excess amount of iron compensates for the evaporation of iron during crystal growth. We concluded that samples grown with the standard method contain iron vacancies of more than 10%. It is considered that increasing the iron in the starting material recovers the iron stoichiometry, and the proper magnetic property appears. With recovery of the chemical stoichiometry, the magnetic hysteresis loop changes from a double loop to a single loop, which indicates the development of spin coherence and the appearance of a large ferrimagnetic domain. The anomaly found in the thermomagnetization curve at approximately 150 K, the so-called TLT transition, disappears with better stoichiometry. This fact indicates that TLT is not a kind of phase transition but an effect of iron vacancy. Our discovery demonstrates that most of the crystals used in RFe2O4 research might contain many iron vacancies. The confused discussions on this material about the spin order model, the charge order model, and so on might reconsider such chemical stoichiometry, including iron vacancies.

    &lt;p&gt;自発分極は試料内部の静電ポテンシャルを傾斜させる。強誘電体の原子軌道エネルギーはこの傾斜に応じて系統的に変化すると考えられる。この現象はバンドベンディングと呼ばれ40年以上に渡り予想されてきた。今回,BaTiO_3_においてバンドベンディング現象を直接的に観測したので報告する。本研究において得られた実験結果は,エピタキシャル製膜された強誘電体薄膜試料と深さ分解光電子分光実験を組み合わせることで初めて達成できた。&lt;/p&gt;

    &lt;p&gt;強誘電体に金属ナノ粒子を接合させると強誘電体の分極により金属の電子状態が変調すると考えられる。電子状態変化が触媒作用に影響することが示唆されているが、電子状態異常の直接的な観測例はない。今回、強誘電体BaTiO_3_表面に担持したPdO_x_ナノ粒子に対してX線吸収微細構造(XAFS)測定を行い、粒子表面で異常な価数状態をとることを見出した、またその発現機構についての考察を行ったので報告する。&lt;/p&gt;

    我々は先に,強誘電体BaTiO3薄膜に対し放射光光源を用いた角度分解光電子分光実験を行い,これまで未知であった傾斜したバンド構造を観測することに成功している。しかし,強誘電体の特異な電子構造は明らかになったばかりであり,強誘電性半導体を用いた電子デバイスの完全設計には至っていない。そこで本研究では,① 傾斜したバンド構造からの電気分極形成機構を解明し,②新しいフェロイックデバイス設計の指針となる,強誘電性半導体物性の解明に取り組む。
    初年度は,誘電性と磁性が共存するマルチフェロック物質においても,電気分極由来の傾斜したバンド構造が存在するのか?および従来型強誘電体に磁性イオンをドープさせることで磁性イオンが強誘電体結晶中でどのように振る舞うのか?の2点に着目して研究を行った。その結果,マルチフェロック物質BiFeO3において放射光源を用いた硬X線角度分解光電子分光法(AR-HAXPES)により,電気分極由来の傾斜バンド構造を初めて観測することに成功した。また,代表的な強誘電体BaTiO3に極低濃度の鉄イオンをドープさせた試料を合成し,その磁性およびバンド構造を明らかにすることができた。前者の成果については2022年6月の国際会議,後者は7月に仏共同研究グループに所属する博士論文公聴会にて発表される。
    このように研究成果は順調に出ているが,研究代表者が仏へ滞在し在外研究を行うことが未だできていない。理由はコロナによる海外渡航の制限によるもので,遅れながら2022年春には渡航を予定していたがウクライナ情勢もあること,仏共同研究グループの博士課程学生の研究を優先させために遅れが生じている。そのため日本で行う実験を前倒しして行い,その分の成果は出ているので研究内容に遅れはない。

    本研究では,光照射下で成長する銀樹状構造について,その作製条件と形状・サイズとの関係を明らかにする.新しく得られた知見に基づき,フラクタル形状を特徴付ける「フラクタル次元」と「世代数」が制御された銀樹状構造を光照射下で成長させることのできる大面積加工技術を確立する.さらに,フラクタル次元と世代数の揃った銀樹状構造を用いて,可視からテラヘルツ波といった広帯域においてフラクタル形状に特徴的な光学応答を探究する.
    初年度は,新たに青,緑,赤,近赤外CWレーザーを購入し,光を照射しながら銀樹状構造を成長させることのできる光学系を構築した.本光学系を用いて,照射光強度を変えながらナノプレートをシードとして用い,緑レーザー照射下で銀樹状構造を成長させたところ,フラクタル次元の低い構造や2本の枝が並走するように伸びた構造などが見られた.また初年度は,銀樹状構造の観察や光学的性質を評価するために必要となる基盤技術も研究した.置換めっきを利用して,銀樹状構造を金樹状構造へと変換する技術や銀樹状構造表面をシリカ薄膜で被覆する技術を開発した.これらの技術は表面増強ラマン散乱(SERS)応用に有効である.SERS計測の高感度化についても検討した.1体の銀樹状構造で532 nmと785 nmの励起波長を用いてSERSマッピングを測定して波長の違いによる増強電場の分布の違いを観測したり,アミノ酸のSERSスペクトル形状変化についても検討した.銀樹状構造のテラヘルツ域での光学応答を調べるために,銀樹状構造をPMMAに包埋する技術を開発した.銀樹状構造をPMMAに包埋することにより,個々の構造が凝集することなく,分散した状態でテラヘルツ光の透過率を測定できる.

    圃場から水域への土壌流亡(炭素流亡)は世界的環境問題であり過去60年以上の研究蓄積にも拘わらず未解決である.本研究は天然ゴムラテックス(以下,天然ラテックス)の特性・利点(高い凝集能,カーボンニュートラルなど)を生かし問題解決に挑戦する.現状では天然ラテックスによる土壌流出特性や土壌環境変化とそれらの制御に関する研究は殆どない.研究チームは,水文学,土壌物理学,固体化学を専門とし,天然ラテックスによる土壌物理化学特性変化や土壌流亡抑制(炭素貯留)効果を評価する.
    令和4年度はタイ2圃場から採取された土壌(Sandy loam,Red clay)とタイ産の天然ラテックスを用いて実験を実施した.輸入した土壌量が限られるため小型の実験装置を構築した.構築した実験装置を用いて,降雨強度20㎜/hと50mm/hの条件下において,表面流出量と浸透量を計測し,天然ラテックス混和の有無および土壌種類の違いによる影響を評価した.その際,時間経過による影響も評価するため,24時間経過後に同一実験を繰り返した.
    その結果,降雨強度20mm/hの場合,天然ラテックスを土壌に混和することで,表面流出量が減少し,浸透量が増加する傾向が伺えた.特に,Sandy loamでその傾向が顕著に観測された.また24時間経過後に実施した実験においても同様の傾向であった.一方,降雨強度50mm/hの場合では,表面流出量の方が浸透量よりも顕著に大きく,天然ラテックス混和の有無による差異は小さいことが分かった.

    本研究は、誘電体において電場が誘起する熱現象を詳らかにし、誘電体の熱制御の方法や熱応答の理解の刷新を狙うものである。本年度は、サーモグラフィ法を用いて誘電体における縦熱電効果(電場と熱流方向が平行)の温度依存性および物質依存性の計測、そしてその定量化を目指した取り組みを行った。特に、交流サーモグラフィ計測における定量性の確保のため、評価・実験面での取り組みに力を入れた。実験結果の議論を行うためには、交流熱応答から適切な物理量を定量的に抽出する必要があり、既知の電気熱量効果をモデルとして評価法の構築に取り組んだ。熱リークや電気熱量効果そのものの周波数依存性を取り入れた評価法を検討した結果、赤外線カメラ自体の応答の補正も組み入れる必要性が分かった。これに対応した交流サーモグラフィ計測評価法を完成させ、電気熱量効果を対象として論文として公表する準備を進めた。実験面では、誘電体試料の電極および配線の間の接触状態によって、対象とする効果の温度変化量が変わる懸念があり、サーモグラフィ計測および高電圧印加と両立するプロービングシステムを設計し、準備を進めた。また、計画していた異種誘電体接合系における実験も進めた。電気的特性および機械的特性は問題なく、今後詳細な熱測定と解析を進める予定である。加えて、新たに物質依存性測定の一環として開始した単結晶試料を用いた実験においても進展があった。その熱信号は非自明な空間分布を有しており、縦熱電効果において誘電秩序の果たす想定外の役割がある可能性がある。これを明らかにすべく、可視光用の測定系をサーモグラフィと組み合わせた赤外-可視同時計測にも取り組んだ。

    Angle-resolved hard x-ray photoemission spectroscopy (AR-HAXPES) has been performed on a skewed electronic structure in ferroelectric thin films. The slope of the skewed band could be changed by switching the polarization. In our experiment, an electronic structure skewed by the electric polarization of ferroelectric is revealed by the binding energy shift of atomic orbitals. All atomic orbitals show similar behaviors, but the magnitude of the energy shift is different. We attributed the electric polarization in the ion crystal to the atomic contribution. Born effective charges, which are different from nominal ionic charges, are defined by the actual amplitude of the polarization divided by the ionic displacement. We found that the magnitude of the energy shift of each atomic orbital has a good correlation with the Born effective charge. These findings lead to a better understanding of the origin of electric polarization.

    RFe2O4 is expected as a next-generation multiferroic material. We attempted to synthesize its single-crystalline film by the sputtering method. As a result, the in-plane orientation of the RFe2O4 layer on the sapphire substrate rotates 30 ° depending on the presence of the Fe3O4 buffer layer. When Fe3O4 and RFe2O4 are laminated to form a multilayer film, the in-plane orientation also depends on their stacking order. In addition, when using the YSZ single crystal substrate, we succeeded in obtaining an RFe2O4 thin film that does not have twin domains and is almost completely composed of single domains.

    In recent years, applications of magnetic nanoparticles in various fields are expected. We found that LaFeO3 nanoparticles having almost no magnetization in bulk form showed large magnetization at low temperatures. Therefore, it should be worth to clarify the mechanism of the induced magnetization systematically to evaluate the relationship between the crystal structure and magnetic properties of LaFeO3 nanoparticles. As a first step, we tried to prepare LaFeO3 nanoparticles with a uniform particle size distribution by using salt-assisted spray pyrolysis. The salt-assisted spray pyrolysis has been expected to synthesize complex oxide nanoparticles with single nanometric sizes.

    液体ガラス転移のダイナミクスの本質が理解されていないのは、その巨視的性質が実に様々なスケールを持つ運動過程により支配されているためである。平成17年度、比熱測定・周波数領域での誘電測定・光散乱実験では充分観測できなかった複雑液体中でのミクロな動的機構を、フェムト秒パルスレーザーを用いた光カー効果(OKE)を利用したコヒーレントフォノン励起法を用いることで直接時間領域での観測できるシステムの構築を試みた。OKEにヘテロダイン検波システムを取り入れたOHD-OKEシステムを立ち上げを行い、液体中のミクロなゆらぎを観測する事に成功した。平成18年度においては液体ガラス転移を示す系のひとつである水・エタノール二成分混合系に注目した。水・エタノールにおいてはまず低振動領域に現れる揺らぎを前年度にOKEにて観測したが、二成分混合系においては水・エタノール間にできる複雑な水素結合のネットワークが重要と考え特に水素結合間の揺らぎに注目した。そこで低振動領域(長時間領域)とは対照的に高振動数領域(短時間領域)に観測される水素-酸素(OH)結合の揺らぎはラマン散乱実験によって観測した。なおOH結合の揺らぎを他の内部振動モードから分離するために重水素置換した重水溶液にて行った。その結果、OH結合の揺らぎには特徴的な水・エタノール濃度依存性がある事がわかった。エタノール低濃度側においては、水・エタノール分子間をつなぐ水和シェル構造が堅固に構成されており、その構造は濃度によらず支配的である。一方、エタノール濃度が増していくと水・エタノール分子間をつなぐ水素結合のネットワークは連続的に変化していった。さらに永和シェル構造などミクロな領域で形成されるクラスターの大きさはエタノールよりアルキル基の多いブタノールなどに比べ小さい事も見積もられた。過冷却状態下で低振動領域に現れる揺らぎの詳細を明らかにすることでモード結合理論の定量的解析をするまでにはまだ至っていないが、今回ミクロな描像が明らかになった水・エタノール二成分混合系を対象に研究を進めていく計画である。
