Prolonged photo-carriers generated in a massive-and-anisotropic Dirac material
Munisa Nurmamat, Yukiaki Ishida, Ryohei Yori +8
Transient electron-hole pairs generated in semiconductors can exhibit unconventional excitonic condensation. Anisotropy in the carrier mass is considered as the key to elongate the…
Direct evidence of hidden local spin polarization in a centrosymmetric superconductor LaOFBiS
Shi-Long Wu, Kazuki Sumida, Koji Miyamoto +9
Conventional Rashba spin polarization is caused by the combination of strong spin-orbit interaction (SOI) and spatial inversion asymmetry. However, Rashba- and Dresselhaus-type spi…
Coexistence of localized and itinerant electrons in BaFe2X3 (X = S and Se) revealed by photoemission spectroscopy
D. Ootsuki, N. L. Saini, F. Du +4
We report a photoemission study at room temperature on BaFe2X3 (X = S and Se) and CsFe2Se3 in which two-leg ladders are formed by the Fe sites. The Fe 2p core-level peaks of BaFe2X…
Realization of bulk insulating property and carrier manipulation in reversible spin current regime of the ideal topological insulator TlBiSe2
Kenta Kuroda, Gaku Eguchi, Kaito Shirai +10
The surfaces of three-dimensional topological insulators (TIs) characterized by a spin-helical Dirac fermion provide a fertile ground for realizing exotic phenomena as well as havi…
Experimental verification of the surface termination in the topological insulator TlBiSe using core-level photoelectron spectroscopy and scanning tunneling microscopy
Kenta Kuroda, Mao Ye, Eike F. Schwier +10
The surface termination of the promising topological insulator TlBiSe has been studied by surface and bulk sensitive probes. Our scanning tunneling microscopy has unmasked fo…
Relocation of the topological surface state of BiSe beneath the surface by Ag intercalation

M. Ye, S. V. Eremeev, K. Kuroda +15
Quasiparticle interference induced by cobalt adatoms on the surface of the topological insulator BiSe is studied by scanning tunneling microscopy, angle-resolved photoe…
Experimental verification of PbBiTe as a 3D topological insulator
K. Kuroda, H. Miyahara, M. Ye +15
The first experimental evidence is presented of the topological insulator state in PbBiTe. A single surface Dirac cone is observed by angle-resolved photoemission spect…
Surface Scattering via Bulk Continuum States in the 3D Topological Insulator BiSe
Sunghun Kim, M. Ye, K. Kuroda +11
We have performed scanning tunneling microscopy and differential tunneling conductance () mapping for the surface of the three dimensional topological insulator BiSe$_…
