Evidence for Oxygen Holes due to d-p Rehybridization in Thermoelectric Sr_{1-x}Rh_{2}O_{4}
Y. Ishida, T. Baba, R. Eguchi +8
Soft-x-ray photoemission and absorption spectroscopies are employed to investigate the electronic structures of Sr_{1-x}Rh_{2}O_{4}. Similarly to the layered cobaltates such as Na_…
Fermi surfaces, electron-hole asymmetry and correlation kink in a three-dimensional Fermi liquid LaNiO
R. Eguchi, A. Chainani, M. Taguchi +6
We report the three-dimensional (3-D) momentum-resolved soft x-ray photoemission spectroscopy of the Fermi liquid LaNiO. The out-of-plane and in-plane cuts of the 3-D electron-…
Combining photoemission and optical spectroscopies for reliable valence determination in YbS and Yb metal
M. Matsunami, A. Chainani, M. Taguchi +13
Hard x-ray photoemission and optical spectroscopies have been performed on YbS and Yb metal to determine the precise -electron occupation. A comparison of the photoemission spec…
Coherent and Incoherent States of Electron-doped SrTiO3
Y. Ishida, R. Eguchi, M. Matsunami +7
Resonant photoemission at the Ti 2p and O 1s edges on a Nb-doped SrTiO3 thin film revealed that the coherent state (CS) at the Fermi level (EF) had mainly Ti 3d character whereas t…
Revisiting the valence-band and core-level photoemission spectra of NiO
M. Taguchi, M. Matsunami, Y. Ishida +10
We have re-examined the valence-band (VB) and core-level electronic structure of NiO by means of hard and soft x-ray photoemission spectroscopy (PES). The spectral weight of the lo…
Photoemission evidence for a Mott-Hubbard metal-insulator transition in VO
R. Eguchi, M. Taguchi, M. Matsunami +15
The temperature () dependent metal-insulator transition (MIT) in VO is investigated using bulk sensitive hard x-ray ( 8 keV) valence band, core level, and V 2 re…
