Spin-polarized angle-resolved photoelectron spectroscopy of the so-predicted Kondo topological insulator SmB6
Shigemasa Suga, Kazuyuki Sakamoto, Taichi Okuda +13
Undoped and slightly Eu-doped SmB6 show the opening of a gap with decreasing temperature below ~150 K. The spectral shapes near the Fermi level (EF) at 15 K have shown strong incre…
Prominent 5d-orbital contribution to the conduction electrons in gold
A. Sekiyama, J. Yamaguchi, A. Higashiya +9
We have examined the valence-band electronic structures of gold and silver in the same column in the periodic table with nominally filled d orbitals by means of a recently develope…
Polaronic behavior of photoelectron spectra of Fe3O4 revealed by both hard X-ray and extremely low energy photons
Masato Kimura, Hidenori Fujiwara, Akira Sekiyama +14
Hard X-ray and extremely low energy bulk-sensitive photoelectron spectroscopy has been performed in the temperature range of 100-330 K for Fe3O4. In the high temperature phase just…
Different Evolution of Intrinsic Gap in Kondo Semiconductors SmB6 and YbB12
J. Yamaguchi, A. Sekiyama, M. Y. Kimura +17
Dependence of the spectral functions on temperature and rare-earth substitution was examined in detail for Kondo semiconductor alloys Sm1-xEuxB6 and Yb1-xLuxB12 by bulk-sensitive p…
Evidence for the constancy of U in the Mott transition of V2O3
H. Fujiwara, A. Sekiyama, S. -K. Mo +10
We have performed high-resolution hard X-ray photoemission spectroscopy for the metal-insulator transition (MIT) system (V(1-x)Cr(x))2O3 in the paramagnetic metal, paramagnetic ins…
