    Abstract

    Nonreciprocal transport phenomena, indicating that forward and backward flows are inequivalent, have been studied mainly in terms of electric conduction in low-symmetry conductors. Although a similar nonreciprocal transport is expected for thermoelectric transport, that is, the Seebeck effect, its experimental studies on bulk crystals are still rare. Herein, we aim to obtain an experimental signature of the nonreciprocal Seebeck effect in the layered ferroelectric semiconductor α-In 2 Se 3 . Thermoelectric voltage signals induced by sinusoidal heater current (sinωt) include cos2ωt and cos4ωt contributions, the ratios and signs of which are consistent with the expected trends of the nonreciprocal Seebeck effect.

    Recently, scanning photoemission microscopy has been combined with angle-resolved photoemission microscopy (ARPES) to enable nano-ARPES measurements with high spatial-resolution. In this research, we have utilized nano-ARPES to conduct surface-selective ARPES measurements of a quasi-1D crystal β-Bi&lt;sub&gt;4&lt;/sub&gt;I&lt;sub&gt;4&lt;/sub&gt;. Our ARPES results reveal that the quasi-1D topological surface states present only on the side surface of the crystal and hence β-Bi&lt;sub&gt;4&lt;/sub&gt;I&lt;sub&gt;4&lt;/sub&gt; is the first weak topological insulator confirmed by ARPES experiments.

    In order to investigate the local magnetic properties of high-T<FONT SIZE="-1">c</FONT> superconductors, we have performed scanning superconducting quantum interference device (SQUID) microscopy (SSM) on the ab-surfaces of an underdoped La<FONT SIZE="-1">1.9</FONT>Sr<FONT SIZE="-1">0.1</FONT>CuO<FONT SIZE="-1">4</FONT> (LSCO) single crystal (T<FONT SIZE="-1">c</FONT>=26 K) at various temperatures. The obtained magnetic images below T<FONT SIZE="-1">c</FONT> clearly demonstrated diamagnetic behavior together with trapped vortices in units of Φ<FONT SIZE="-1">0</FONT> (= hc/2e). Above T<FONT SIZE="-1">c</FONT> up to 97 K, on the other hand, we did not observe any magnetic structures within an experimental error of ≤0.2 μT, contrary to the recent SSM results of LSCO thin films exhibiting diamagnetic regions of over-micron scales. From the present SSM observations, it can be safely said that local diamagnetism of such scales is unique to thin film specimens.

    超高速キャリア移動度(μ∝τ/m*)を実現するために、物質固有の電子有効質量(m*)を極端に小さくできるグラフェンに類似した線形電子分散(ディラック型)および派生した特徴的な電子構造(ワイル型、ノーダルライン型、ノーダルリング型など)をもつ半金属を、第一原理計算を活用しながら開発した。
    初年度として、精密物性値計測の強化に向けた測定システムのアップグレードや、単結晶をマイクロデバイス化して測定信号の増強を図る手法の開発なども進めた。
    選定を進めていた候補物質について、化学組成や欠陥量を精密制御した純良単結晶試料の準備に取り組み、キャリア移動度や磁気抵抗変化率を含めた磁気輸送特性の詳細な評価を行った。
    研究戦略に沿った計画が順調に進み、具体的に研究対象とした物質群として論文発表まで行うことができたものが、Bi4Br4 [Nature Materials]、(Sn,Bi,Sb)2Te2S [Appl. Phys. Lett.]、(Bi,Sb) [J. Phys. Soc. Jpn]、Mo(Te,Se)2 [Phys. Rev. B]、CoNb3S6 [Phys. Rev. B]、PbTaSe2 [Nature Commun.] など多岐にわたった。

    新概念の提案が理論から続くトポロジカル電子物質を対象として、マテリアルズ・インフォマティクス(MI)を活用しつつ、そのスキームだけでは探索・開拓することが難しい物質群の開発に挑戦している。
    ① MIから発掘するスジの良い化合物(「経験」と「勘」に基づく実績を活かし新概念へ発展)
    ② 現状のMIでは見逃してしまう化合物(複数フェルミ面系、構造敏感な電子相、低次元系など)
    ③ 今後のMIでも扱うことが難しい化合物(構造非対称系、磁性系、強相関系、超伝導系など)
    などを独自の物質・現象・物性・機能の開拓を行う戦略として設定し、「第一原理計算」「純良単結晶育成」「先端分光計」「極限環境物性評価」を武器として実証実験を推進した。
    特筆すべき成果としては、中身(3D)と表面(2D)は絶縁体であるが縁(1D)には特殊金属状態を生ずる「高次トポロジカル絶縁体」として Bi4Br4 を確立できたこと [Nature Materials] や、対称性の保護によって運動量空間の高対称点に電子状態が縮退した「クラマースワイル半金属」として CoNb3S6 を確立できたこと [Phys.Rev.B]、空間反転の破れた PbTaSe2 の超伝導状態においてダイオード的な挙動を発見したこと [Nature Commun.] 、歪みでトポロジカル電子相の転移が生ずる TaSe3 を発見したこと [Nature Materials]、伝導電子が局在スピン・軌道の複合自由度と強く相互作用することで現れる「多極子ポーラロン」の準粒子状態をもつ CeSb を発見したこと [Nature Materials] などが挙げられる。

    With the aim of creating ``skyrmionics", (electronics utilizing magnetic skyrmions), we have worked on (1) search for materials and systems which host skyrmions, designing methods to control and manipulate skyrmions, and search for new physical phenomena and material functions of skyrmions. We have achieved several important discoveries and results for each of these items. In addition, while research aimed at application of skyrmions as information carriers in magnetic memory devices are conducted, we have discovered that magnetic skyrmions have high potential for applications to reservoir-type information processing devices and thermoelectric devices, opening up a new development in the skyrmion research. In addition, we have developed our research into new topological magnetic textures other than skyrmions (e.g., skyrmion bags, bimerons, hopfions, (anti)hedgehogs).

We developed both new compounds and novel electronic functionality within a new class of materials called "topological insulators, topological semimetals, and topological superconductors". With regard to materials, phenomena, and functions, several unexpected discoveries were made, which were puplised as 45 articles in high-impact-factor journals, including 5 articles in Nature and sister journals.

    In order to improve and explore the functionality of diamond molecules (or the so-called diamondoids), a dipole moment was introduced by the chemical substitution of oxygen or halogen (F, Cl, Br, I) for hydrogen. Synthesis of such "polar diamond molecules" containing one and two diamond-cage(s) was successfully performed, which was confirmed by good agreements between the theoretical calculations based on first-principles and the measured infrared spectra of the purified obtained materials. As a result, six kinds of non-commercially available polar diamond molecules were successfully obtained with sufficient yields for the measurements of their physical properties.
    We found a dielectric anomaly associated with the freezing of the molecular rotation in the crystal, which showed systematic temperature shift reflecting the size (rotational barrier) of the substituted atom.

    In order to understand the unusual electronic states emerging in strongly correlated electron systems such as high temperature superconductivity and colossal magneto-resistance, we combined time-resolved femotosecond optical and resonant X-ray diffraction measurements on transition metal compounds having (stripe-type) charge and spin orderings.
    We were able to reveal unforeseen photoinduced phase fluctuations of the charge order parameter. Relaxation of the phase fluctuations is found to be an order of magnitude slower than that of the order parameter's amplitude fluctuations, and thus limits charge order recovery. This new aspect of phase fluctuations provides a more holistic view of the phase's importance in ordering phenomena of quantum matter.

    Because of the excellent electronic conduction resulting from massless Dirac fermions, Graphene is a promising candidate material for next generation (post-silicon) electronic devices. As a beyond-Graphene technology, we tried to develop both new compounds and novel electronic functionality within a new class of materials called "topological insulators". Highlights of this work are as follows:
    (1) A "polar" topological insulator was for the first time materialized, which could make topological electronic devices quite simple [Nature Physics].
    (2) Unlike Graphene, the massless Dirac fermions in the topological insulators were proved to be quite stable against the imperfection of the materials. It was further demonstrated that the Dirac surface state and associated spin distribution could be locally (in nano-scale) manipulated by the bias voltage and magnetic field [ACS Nano, Nature Physics].

    We have used spectroscopic imaging scanning tunneling microscopy to investigate the superconducting gaps and the electronic states of the iron-based superconductors LiFeAs and FeSe. We found that some defects in LiFeAs generate in-gap bound state. We also examined the effects of twin boundaries on the superconducting gap of FeSe and found that the twin boundary induces a novel superconducting state that breaks the time-reversal symmetry. The band dispersions of FeSe were determined by the quasi-particle interference effect. The estimated Fermi energy is smaller than 10 meV, being of the same order as the superconducting gap. This means that FeSe is in the BCS-BEC crossover regime. The observed quasi-particle interference patterns possess strong in-plane anisotropy which may reflect the orbital ordering in this material.

    ダイヤモンドの結晶構造に特徴的な炭素のカゴ型クラスターを骨格にもつ化合物群「ダイヤ分子」は、バルク・ダイヤモンドの優れた物理的特性を受け継ぎつつ、ナノのサイズや特徴的な形状、高い対称性に起因した付加的電子機能を発現する可能性を秘めた新しい炭素系ナノテク素材である。全ての種類のダイヤ分子が室温で固体状態に凝集していることに我々は着目し、その結晶相に特有な新奇物性・電子機能の開拓に、実験と理論計算の双方から取り組んだ。
    研究の前半では、水素終端されたダイヤ分子を対象に詳細な研究を行った。光学応用に有用な性質として、バルク・ダイヤモンドの間接遷移型バンドギャップがダイヤ分子結晶では直接遷移型になりギャップ値もケージ数で系統的に変化すること、高周波用の低損失な絶縁材料の可能性として誘電率がダイヤモンドに比べて半減すること、ダイヤ分子結晶が紫外光を吸収して蛍光する性質をもつことなどを見出した。また、実験検証の出発点として、ダイヤ分子を高度に精製し大型で純良な単結晶に合成する手法も確立した。
    後半では、終端水素の化学置換により双極子モーメントを持つようになった「極性ダイヤ分子」を対象として、新たな研究展開を狙った取り組みを行った。ケトン化およびハロゲン化されたケージ数が1つと2つのダイヤ分子について、単離精製・単結晶化して基礎物性の実験的評価を行うと共に、分子単体および結晶相について第一原理計算による物性予測を進めた。誘電率の温度依存性において、結晶中の分子回転に起因する転移を反映した誘電異常の観測に成功した。これにより、回転のエネルギー障壁や異方性を制御・設計することにより、室温での強誘電性や非線形光学効果などの実現を目指す新たな研究の方向性を示すこともできた。

    石油から抽出できるナノテク新素材「ダイヤ分子」には、ダイヤモンドのもつ優れた性質に加えて、ナノのサイズ、特徴的な形状、キラリティー(構造の右手・左手の関係)などから生ずる新たな機能が期待される。そこで、フラーレンやカーボンナノチューブを凌駕する第3の炭素系ナノ材料とすべく、ダイヤ分子に固有な量子特性や超機能を発掘し、工学的応用への可能性を探ることを目的に、昨年度から引き続き、理論的アプローチと実験的アプローチの双方を活用した多角的な機能開拓を行った。
    ダイヤ分子の結晶が、光の吸放出に有利な直接遷移型の電子バンド構造をもつこと、そのバンドギャップの大きさがダイヤ分子の大きさで調整可能なことを、第一原理に基づく理論計算で昨年度に見出している。今年度は、より高度な計算手法を取り入れて、誘電特性に関する理論計算による検討を進め、ダイヤ分子の結晶が、非常に小さな誘電率をもっており、高周波のデバイスにおける、低損失な絶縁体材料として有望であることを見出した。一方で、良質で大型なダイヤ分子の単結晶試料を作製するための専用の装置と手順の開発を本研究課題で達成したことから、理論予測を実験実証することについても検討が進んだ。実際に、単結晶試料を用いて、マイクロ波を用いた空洞共振法によって誘電率測定を行ったところ、その絶対値も理論予測と良い一致を示すことが確認できた。

    This research project has aimed for the development of semiconductor physics of Mott insulators which are anticipated as key elements of next generation electronics. We have worked on the following subjects in order to clarify experimentally how the principles of semiconductor physics, such as impurity states or interfacial states, are modified in "Mott semiconductors".
    1.Local spectroscopy on Sr_3Ru_2O_7 by STM/STS
    The effect of Mn impurities introduced into Sr_3Ru_2O_7, which is located on the verge of the magnetic and orbital state criticality, was investigated by STM/STS. The length scale of the influence of impurities was found to reach several nm due to the reduced screening of strongly correlated electrons. We also observed the anomalous evolution of electron density of states spectra at the low-energy region, which is related to the metamagnetic instability.
    2. Metal-insulator transition induced by electrostatic carrier doping
    We have designed oxide field-effect transistors with organic gate insulators. By applying this method to SrTiO_3, the prototype perovskite oxide, we have realized the insulator to metal transition by electrostatic carrier doping. In the metallic phase, the carrier mobility exceeds 1000 cm^2/Vs.
    3. Resistive switching memory in binary transition-metal oxides Resistive random access memory (RRAM) is expected as an interfacial device of next generation. However, the mechanism of the resistive switching remains to be elucidated. By fabricating planer-type devices with binary transition-metal oxides and directly observing the interfaces, we evidenced the formation of conducting filament induced by pulse electric fields, and also found that the resistive switching occurs at the interface between the filament and metal electrodes.

    高温超伝導体の電子構造やキャリアダイナミクスに対する格子振動の効果を観測するために、酸素同位体効果に着目した研究を行っている。これにより、遷移金属酸化物に特有な強い電子同士の相互作用に埋没してしまって見逃されがちであった電子と格子の相互作用の詳細な解明を目指している。新奇格子効果の探求とその機構解明を通じて、高温超伝導メカニズムの関連性についての検討を行うことが本研究の最終目的である。
    これまでに実施した研究により、高温超伝導体試料を精密かつ系統的に酸素同位体置換する技術を確立することができた。特に本申請により、この目的に適した専用の特殊な炉を設計し製作できたことの寄与が大きい。角度分解光電子分光測定を、同位体置換前後の試料を対象として行うことで、酸素が関与する格子振動が電子構造やダイナミクスにどのように影響を与えるのかを、運動量空間で直接観察することに成功した。観測された準粒子バンドの同位体置換による変化は、運動量空間と温度に特異な依存性を示すことを見出した。この結果は、単純な金属電子論の予測と一致しないことから、理論にとっても大きなインパクトとなった。更に、電荷とスピンの自己組織化現象に対する格子振動の効果の検討も、非弾性X線散乱実験を用いて開始した。これにより、相競合などが関与した強相関電子系に特有な格子効果や現象の観察が進行しつつある。

    The aim of this research project is to explore the device physics of strongly correlated semiconductors. One of the major targets was the impurity effect. As a prototypical system, lightly doped Mott insulator Ca_<2-x>Na_xCuO_2Cl_2 was studied. We found a non-scale self-organization of electrons associated with doping by STM/STS and finally identified it as a checkerboard type charge ordering, which we believe is at the heart of cuprate physics including large psedo-gap phenomena. We also find nano-scale variation of electronic states around the impurities in nearly ferromagnetic ruthenates, which represents an important step to establish physics of impurity states in strongly correlated electron systems. The other major targets was fabrication of oxide device, in particular field effect transistor (FET). We have successfully fabricated SrTiO_3 perovskite FET, which shows well defined FET characteristics such as the saturation of drain current. Even better performance was achieved in another perovskite oxide KTaO_3, which showed ON/OFF rationof 1000 and the field effect mobility of 0.4 cm^2/Vsec comparable with those of organic FET. These devices can work at a cryogenic temperature as low as 2K and the presence of metallic channel was confirmed. These results opened door for FET "chemistry" of exotic transition metal oxides.

    高温超伝導メカニズム解明を目指して、高温超伝導の発現舞台となっている2次元CuO_2面について、フェルミ準位近傍の低エネルギー領域の電子構造およびダイナミックスに関する知見を得るための実験を行ってきた。本研究の特色は、(1)精密化学組成制御した一連の高温超伝導体単結晶試料の作製、(2)光学スペクトル、走査トンネル顕微鏡/分光(STM/STS)、そして角度分解光電子分光(ARPES)という種々の分光実験手法を組合せた相補的な実験データの収集である。
    対象とした高温超伝導体はCa_<2-x>Na_xCuO_2Cl_2[CNCOC]とLa_<2-x>Sr_xCuO_4[LSCO]である。これらの物質は、単純な結晶構造を持ち、反強磁性絶縁体から超伝導体までの組成(キャリアドープ量)を合成可能なことが利点であることから、超伝導メカニズムと密接に関連しているドープに伴う電子構造の発達過程を明らかにするのに理想的な系と考えた。CNCCOについては、高圧下での特殊な単結晶育成技術を確立することに成功し、初めて単結晶を用いた実験を可能とした。CNCOCの組成xを系統的に変化させた単結晶試料における実験より、キャリアのドープにより、分散関係をほとんど変化させることなく、反強磁性絶縁体である母物質(x=0)のバンドがフェルミ準位へとシフトして金属化(超伝導を発現)している様子を観測した。このような「Rigid Band Shift」的な描像は、母物質のバンドギャップ間にドープに伴って新たな状態が形成されるという、典型的な高温超伝導物質といわれるLSCOにおける観測から、今まで普遍的と考えられていた電子構造の発達過程と大きく異なっている。このように、反強磁性絶縁体から超伝導体に至る道筋は一つではないことを示すことができたことが最大の成果であると考えている。
