The band alignment at the interface is one of the fundamental parameters for designing electronic devices and artificial functional materials. However, there is no firmly established guideline for oxide heterostructures, limiting the functional design of oxide heterostructures. Here, we provide spectral evidence that the band diagram of oxide heterointerfaces is well described by the Zhong and Hansmann scheme based on the common anion rule [Z. Zhong and P. Hansmann, Phys. Rev. X 7, 011023 (2017)]. By utilizing the elemental selectivity of Ti 2p–3d resonant photoemission for the Ti 3d state near the Fermi level, we directly visualize the presence or absence of charge transfer from the overlayer films to SrTiO3 in prototypical heterointerfaces of SrVO3/SrTiO3 and SrNbO3/SrTiO3. It is found that the charge transfer occurs in SrNbO3/SrTiO3 but not in SrVO3/SrTiO3, as predicted by the Zhong and Hansmann scheme, indicating that the presence or absence, as well as the sign and amount, of interfacial charge transfer is predicted by this scheme. Our findings provide guidelines for designing and controlling the functionalities in oxide nanostructures.

Abstract Some oxide nanostructures have recently been shown to host quantum well (QW) states that are promising for quantum device applications by designing the wave function of their strongly correlated electrons. However, it is unclear why QW states only appear in certain oxides, limiting the possibilities of wave-function engineering. Here, we demonstrate that the electron mean free path λ is one of the essential conditions to form standing waves of strongly correlated electrons in oxide nanostructures. We have investigated the QW states formed in SrTi_1–xV_xO₃ (STVO) ultrathin films using in situ angle-resolved photoemission spectroscopy. The controllability of λ in STVO while maintaining an atomically flat surface and chemically abrupt interface enables us to examine the evolution of QW states with varying λ. A detailed analysis reveals that the intensity of the QW states is almost linearly correlated to λ and may disappear at the Ioffe–Regel criterion, corresponding to the nearest neighbor inter-vanadium distance in STVO. Our findings provide design guidelines for creating and controlling novel quantum phenomena in oxide nanostructures.

Abstract To realize practical anode electrode film for solid oxide fuel cells (SOFCs) operating at a medium temperature range, we have prepared c-axis oriented BaCe0.7Ru0.1Y0.2O3-d (BCRY) thin films on an MgO (100) substrate by RF magnetron sputtering. The oxygen vacancies concentration was quantitatively evaluated by X-ray absorption spectroscopy and defect chemical analysis. Proton conductivity was proven from the O 1s photoemission spectrum showing an OH- peak formed on the oxygen ion sites. Electron conductivity was proven from small density-of-state at the Fermi level (EF) and the energy difference between the top of the valence band and the EF, which is close to the activation energy of the conductivity. The wet-annealed BCRY thin film, which exhibit surface electron-proton mixed conductivity of more than 10-3 S/cm at 300 °C, can be applied as a practical anode electrode film with high chemical reaction for SOFC operating in the medium temperature range.

Abstract Vanadium dioxide VO2 thin films can be applied as electrolyte of electric double layer transistor or positive electrode for all-solid-state lithium-ions batteries. In order to verify the charge behavior between the Li+ ion conductor LiCoO2 and VO2, we have investigated the electrical conductivity and electronic structure of b-axis oriented VO2/LiCoO2 multilayer film prepared on Al2O3 (0001) substrates by RF magnetron sputtering. The amount of excess oxygen in the VO2/LiCoO2 multilayer film was evaluated to be ~22.5% by X-ray photoemission spectroscopy. The electrical resistivity of the multilayer film increases with temperature from 290 to 330K, and decreases reversibly above 330K, indicating the Li+ ion conduction. The electron correlation energy of the VO2/LiCoO2 multilayer and VO2 thin film are ~3.4 eV and ~2.4 eV, respectively. These results indicate that the carrier number of the VO2 thin film can control by diffusion of Li+ ions from LiCoO2 buffer layer.

Abstract Topological insulators (TI) hold significant potential for various electronic and optoelectronic devices that rely on the Dirac surface state (DSS), including spintronic and thermoelectric devices, as well as terahertz detectors. The behavior of electrons within the DSS plays a pivotal role in the performance of such devices. It is expected that DSS appear on a surface of three dimensional(3D) TI by mechanical exfoliation. However, it is not always the case that the surface terminating atomic configuration and corresponding band structures are homogeneous. In order to investigate the impact of surface terminating atomic configurations on electron dynamics, we meticulously examined the electron dynamics at the exfoliated surface of a crystalline 3D TI (Bi$$_2$$Se$$_3$$) with time, space, and energy resolutions. Based on our comprehensive band structure calculations, we found that on one of the Se-terminated surfaces, DSS is located within the bulk band gap, with no other surface states manifesting within this region. On this particular surface, photoexcited electrons within the conduction band effectively relax towards DSS and tend to linger at the Dirac point for extended periods of time.

Abstract The Kondo effect between localized f-electrons and conductive carriers leads to exotic physical phenomena. Among them, heavy-fermion (HF) systems, in which massive effective carriers appear due to the Kondo effect, have fascinated many researchers. Dimensionality is also an important characteristic of the HF system, especially because it is strongly related to quantum criticality. However, the realization of the perfect two-dimensional (2D) HF materials is still a challenging topic. Here, we report the surface electronic structure of the monoatomic-layer Kondo lattice YbCu₂ on a Cu(111) surface observed by synchrotron-based angle-resolved photoemission spectroscopy. The 2D conducting band and the Yb 4f state, located very close to the Fermi level, are observed. These bands are hybridized at low-temperature, forming the 2D HF state, with an evaluated coherence temperature of about 30 K. The effective mass of the 2D state is enhanced by a factor of 100 by the development of the HF state. Furthermore, clear evidence of the hybridization gap formation in the temperature dependence of the Kondo-resonance peak has been observed below the coherence temperature. Our study provides a new candidate as an ideal 2D HF material for understanding the Kondo effect at low dimensions.

Abstract Amorphous semiconductors are widely applied to electronic and energy-conversion devices owing to their high performance and simple fabrication processes. The topological concept of the Berry curvature is generally ill-defined in amorphous solids, due to the absence of long-range crystalline order. Here, we demonstrate that the Berry curvature in the short-range crystalline order of kagome-lattice fragments effectively contributes to the anomalous electrical and magneto-thermoelectric properties in Fe–Sn amorphous films. The Fe–Sn films on glass substrates exhibit large anomalous Hall and Nernst effects comparable to those of the single crystals of topological semimetals Fe₃Sn₂ and Fe₃Sn. With modelling, we reveal that the Berry curvature contribution in the amorphous state likely originates from randomly distributed kagome-lattice fragments. This microscopic interpretation sheds light on the topology of amorphous materials, which may lead to the realization of functional topological amorphous electronic devices.

Layered oxides have been intensively studied due to their high degree of freedom in designing various electromagnetic properties and functionalities. While Bi-based layered supercell (LSC) compounds [BinOn+δ]-[MO2] (M = Mn, Mn/Al, Mn/Fe, or Mn/Ni; n = 2, 3) are a group of prospective candidates, all of the reported compounds are insulators. Here, we report on the synthesis of two novel metallic LSC compounds [BinOn+δ]-[RhO2] (n = 2, 3) by pulsed laser deposition and subsequent annealing. With tuning the thickness of the sublattice from Bi2O2+δ to Bi3O3+δ, a dimensionality-dependent electrical transport is revealed from a conventional metallic transport in n = 2 to a localized transport in n = 3. Our successful growth will be an important step for further exploring novel layered oxide compounds.

More details Close

Anatase TiO<inf>2−δ</inf>thin film was prepared by RF magnetron sputtering using oxygen radical and Ti-metal target. Degrees of the TiO<inf>2−δ</inf>crystal orientation in the thin film depends of the oxygen gas pressure ([Formula: see text]) in the radical gun. The (004)- and (112)-oriented TiO<inf>2−δ</inf>thin films crystallized without postannealing have the mixed valence Ti⁴⁺/Ti³⁺state. The electrical conductivities, which corresponds to n-type oxide semiconductor, is higher in the case of (004)-oriented TiO<inf>2−δ</inf>thin film containing with high concentration of oxygen vacancy. The donor band of TiO<inf>2−δ</inf>thin film is observed at ∼1.0 eV from the Fermi level (E<inf>F</inf>). The density-of-state at E<inf>F</inf>is higher in (004)-oriented TiO<inf>2−δ</inf>thin film. The above results indicate that the oxygen vacancies can control by changing the [Formula: see text] of the oxygen radical.

We developed a cryocooled YBCO vector magnet system for X-ray magnetic circular dichroism (XMCD) measurements. This system can generate a two-dimensional vector-controllable magnetic field in any chosen direction using two external power supplies and vary the photon polarization. The magnet mounted in the system is cryogen-free and conduction-cooled, and consists of two-axial split coils. The material of the coils is YBCO tape conductor. The peak vector magnetic field of 1.2 T is obtained. In this report, we describe specifications of the system, cooling and operating test results and XMCD measurement results using the system.

The Se-doped SrTiO₃ (SrTi_1-xSc_xO_3-δ) thin films have prepared on Nb-doped SrTiO₃ (100) substrates by RF magnetron sputtering. The thin film deposited at the substrate temperature of 500°C exhibits highly α-axis orientation. The as-deposited thin film consists of grain with a diameter of ～60 nm and smooth surface. The electrical conductivity exhibits hole conduction at low temperature region below 400°C and oxygen ion conduction at high temperature region above 550°C. The activation energy at the low temperature region, which is estimated from the Arrhenius plot of the electrical conductivity, is in a good agreement with the energy separation between the top of the valence band and the Fermi level.

We have investigated the thermal stability of TiN/HfSiON gate stack structures using synchrotron-radiation photoemission spectroscopy. Spectral intensities of the Si-oxide components in Si 2p core-level spectra systematically increase with annealing temperature, which strongly depends on thickness of the TiN metal gate layer. Changes brought by annealing procedures in in-depth profiles indicate segregation of Si atoms at the TiN surface. Furthermore, chemical-states-resolved in-depth analyses by angle-resolved photoemission spectroscopy suggest formation of TiSi_x and HfN_y components, due to chemical bond breaking in the HfSiON layer during TiN film growth. This can be related to the degradation of thermal stability.

Angle-resolved photoemission spectroscopy (ARPES) is a powerful experimental tool for revealing the electronic band structure of solids. Excellent characteristics of synchrotron radiation light enable us to achieve specialized ARPES measurements. In order to perform such experiments, we have constructed a new beamline BL-2 MUSASHI (Multiple Undulator beamline for Spectroscopic Analysis of Surface and Hetero-Interface) at Photon Factory, KEK. As examples of the specialized ARPES measurements by utilizing the advantage of this beamline, we introduce recent ARPES results on ( 1 ) three-dimensional electronic structures with changing the photon energy, ( 2 ) bulk electronic structures using high energy soft x rays, and ( 3 ) orbital-selective electronic structures by polarization dependent ARPES measurements.

複雑な磁気構造に代表される異常物性が報告されているCeSbについて、その常磁性相と反強常磁性相における電子状態を調べるために高分解能角度分解光電子分光を行った。常磁性相(30K)から反強常磁性相(10K)にかけて、Γ点付近のSb5p<3/2>からなるホール・ポケットと、X(M)点付近に存在するCe5d<t2g>によるエレクトロン・ポケットが大きくなるといった相転移に伴うバンド構造の変化を初めて角度分解光電子分光法でとらえることに成功した。この結果はp-fmixing model による予測と定性的に一致し、CeSbの示す複雑な磁気構造が、その特徴的なバンド構造と密接な関係があることを示している。

La_1/3_Sr_2/3_FeO_3_薄膜は特徴的な電荷、磁気秩序を示すことが知られている。電荷秩序に対して硬X線散乱、磁気秩序に対して共鳴軟X線散乱を適用してピーク強度の温度変化、相関長を調べた。さらにすれすれ入射を用いて表面での磁気秩序の相関長を得た。その結果、面直方向、面内方向ともにその相関長は膜厚に比例して減少する傾向が見られた。表面近傍における転移温度は薄膜の転移温度と違いは見られなかった。

More details Close

We have developed a new method to evaluate chemical states, band offsets and crystallized states of SiO_2, SiN and HfO_s gate insulators by taking advantages of high brightness and variable photon energy of synchrotron radiation. We have evaluated band offsets of SiO_2, SiN, and high-k insulators by the combination of photoelectron spectroscopy and x-ray absorption spectroscopy, in comparison with energy-loss spectroscopy. Furthermore, we have found that valence band photoelectron spectra and x-ray absorption spectra can provide the qualitative information on crystallization states during in situ annealing.

La1-xSrxMnO3 (LSMO)単結晶薄膜のin-situ角度分解光電子分光を行い、この薄膜のバンド構造を実験的に決定することに成功した。この結果から、LSMO x=0.4においてフェルミ準位近傍にΓ点を中心とした電子ポケットを明確に観測し、これがホールの減少に伴って徐々に消失していくことを見出した。さらに、この変化がLSMOのホールドープに伴う金属ー絶縁体転移の起源であると結論づけた。

We have performed photoemission spectroscopy and x-ray absorption spectroscopy of HfO_2 gate insulators to investigate the annealing effect of chemical states and electronic band structures systematically. Comparing the line shapes of core-level photoemission spectra for two systems with and without Hf-metal predeposition, we have found that Hf-metal predeposition reduces the segregation of SiO_2 and Hf-silicide. Hf 4 f core-level spectra revealed that the annealing at 1000℃ causes the phase separation of Hf-metal and Hf-silicide in clusters segregated at Si surface. In the case with the Hf-metal predeposition, valence-band spectra are split into double peaks and the line shapes of O K-edge x-ray absorption spectra become sharp by annealing at 800℃ and 900℃, suggesting the crystallization of the Hf0_2 layer.

High-resolution photoelectron spectroscopy using very bright undulator synchrotron radiation has been performed for ultrathin gate insulators such as Si oxynitride, Zr0_2 and Hf0_2 films. The chemistry of nitrogen atoms in Si oxynitride films is clearly elucidated and band offsets are precisely determined by the substrate information subtraction method. The dependence of valence band and conduction band offsets on nitrogen concentration in Si oxynitride films is clarified, and the band offsets of Zr0_2 and HfO2 films with double layer structures are determined.

The transition-metal oxides, such as titania and hematite, are conventional materials utilized in various electrochemical cells because of their non-toxic, earth-abundant, and stable nature. This research aims at adding new electrochemical functionalities to them by combining the power of epitaxial growth techniques and newly developed phase-diagram analysis method. We implemented a compact electrochemical cell to test a number of thin-film samples. Representative achievements are summarized as follows: (i) band-gap narrowing in ferrite based films and orientation control of hematite films resulted in substantial improvement of visible-light driven photoelectrochemical water oxidations; (ii) complete and reversible superconductor-insulator transitions in lithium titanate films were achieved by Li-ion electrochemical reactions; (iii) superconductivity in higher titanium oxides films was discovered. Our approach is a powerful way to find new functionalities for sustainable society.

We have succeeded in synthesis of four new double-perovskite oxides, each of which exhibits high degree of order in the arrangements of different transition-metal atoms, to reveal their ground-state magnetic order. Also, photoanodes consisting of epitaxial films of transition-metal oxide solid-solutions have been developed to demonstrate visible-light water oxidation enhanced via metal-to-metal charge-transfers. Moreover, using electrochemical Li-ion doping technique, we have realized reversible superconductor-insulator transition in a Li-containing titanate. These studies can be recognized to bring new trend in the framework of “oxide electronics”, and further development of functional oxide materials owing to their characteristic electronic structures is expected.

Interfaces, superlattices, and ultra-thin films consisting of different correlated electron materials have attracted intensive interest in recent years because of their novel physical properties that are not present in the constituent materials. However, because their volumes are tiny compared to the volumes of the samples, conventional measurements of the physical properties are difficult or impossible. On the other hand, spectroscopic measurements using synchrotron radiation in the soft x-ray region are powerful tools because of their probing depths on the nanometer scale. In the present project, we have developed a measurement system in which the light polarization and the applied magnetic field direction can be varied independently. By combining this system with our in-situ photoemission measurement system, we have successfully observed novel metal-insulator transitions, quantized levels, and magnetic anisotropies of oxide interfaces, superlattices, and ultra-thin films.

In order to investigate chemical, electronic and magnetic structures in nano-devices, environmental catalysts and other inhomogeneous systems, we have developed nano-spectroscopy using two types of photoelectron microscopy, namely projection type and scanning type, with synchrotron radiation, and have applied them to LSI nanostructures, magnetic nanostructures, resistance RAM and non-Pt catalysts successfully. We have achieved the following eight points. 1. Projection-type PEEM was modified to improve the spatial resolution up to 22 nm by means of anti-vibration setup and image processing software for sample drift correction. 2. Scanning-type 3DnanoESCA was developed with spatial resolution of 92 nm by pin-point angle-resolved photoelectron spectroscopy. 3. Magnetic imaging by XMCD-PEEM was realized for permalloy nanostructures and patterned LSMO nanostructures for non-volatile magnetic memory applications. 4. In situ imaging by PEEM was realized for LSI high-k gate insulators during vacuum annealing. 5. Pin-point in-depth analysis by 3DnanoESCA was realized for LSI high-k gate insulators. 6. PEEM imaging at Cu L edges for CuO and Cu revealed the ReRAM mechanism with reduction/oxidation switching. 7. Micro XAS at Pt and Co absorption edges for tapered-cut anode/electrolyte/cathode of fuel cells revealed the degradation mechanism. 8. Hard X-ray PEEM enabled the visualization of deeply embedded Au nano-patterns.
