Observation and control of the weak topological insulator state in ZrTe5
Peng Zhang, Ryo Noguchi, Kenta Kuroda +14
A quantum spin Hall insulator hosts topological states at the one-dimensional edge, along which backscattering by nonmagnetic impurities is strictly prohibited and dissipationless…
Material design with the van der Waals stacking of bismuth-halide chains realizing a higher-order topological insulator
Ryo Noguchi, Masaru Kobayashi, Zhanzhi Jiang +28
The van der Waals (vdW) materials with low dimensions have been extensively studied as a platform to generate exotic quantum properties. Advancing this view, a great deal of attent…
Rashba spin splitting of L-gap surface states on Ag(111) and Cu(111)
Koichiro Yaji, Ayumi Harasawa, Kenta Kuroda +4
Spin-resolved band structures of L-gap surface states on Ag(111) and Cu(111) are investigated by spin- and angle-resolved photoelectron spectroscopy (SARPES) with a vacuum-ultra-vi…
Giant Rashba splitting of quasi-1D surface states on Bi/InAs(110)-(21)
T. Nakamura, Y. Ohtsubo, Y. Yamashita +10
Electronic states on the Bi/InAs(110)-(21) surface and its spin-polarized structure are revealed by angle-resolved photoelectron spectroscopy (ARPES), spin-resolved ARPES,…
Discovery of switchable weak topological insulator state in quasi-one-dimensional bismuth iodide
R. Noguchi, T. Takahashi, K. Kuroda +16
The major breakthroughs in the understanding of topological materials over the past decade were all triggered by the discovery of the Z topological insulator (TI). In three dim…
Direct Mapping of Spin and Orbital Entangled Wavefunction under Interband Spin-Orbit coupling of Rashba Spin-Split Surface States
Ryo Noguchi, Kenta Kuroda, K. Yaji +6
We use spin- and angle-resolved photoemission spectroscopy (SARPES) combined with polarization-variable laser and investigate the spin-orbit coupling effect under interband hybridi…
