Optical and photoelectrical studies on anisotropic metal-insulator transition of RuAs
Yuki Nakajima, Zenjiro Mita, Hiroshi Watanabe +6
The anisotropic changes in the electronic structure of a metal-to-insulator transition (MIT) material, RuAs, with two-step phase transition are reported by using polarized optical…
Anomalous Superconducting-Gap Structure of Slightly Overdoped Ba(FeCo)As
T. Hajiri, T. Ito, M. Matsunami +3
We observed the anisotropic superconducting-gap (SC-gap) structure of a slightly overdoped superconductor, Ba(FeCo)As (), using three-dimensional (…
Polarization-Dependent Three-Dimensional Angle-Resolved Photoemission Spectroscopy of BaFeCoAs
Tetsuya Hajiri, Takahiro Ito, Masaharu Matsunami +3
We performed polarization- and photon-energy-dependent angle-resolved photoemission spectroscopy of a slightly overdoped iron pnictide superconductor, BaFeCoAs$_{2}…
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…
Momentum-Dependent Hybridization Gap and dispersive in-gap state of The Kondo Semiconductor SmB6
Hidetoshi Miyazaki, Tetsuya Hajiri, Takahiro Ito +2
We report the temperature-dependent three-dimensional angle-resolved photoemission spectra of the Kondo semiconductor SmB. We found a difference in the temperature dependence o…
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…
