Fermi level tuning of one-dimensional giant Rashba system on a semiconductor substrate: Bi/GaSb(110)-(2x1)
Takuto Nakamura, Yoshiyuki Ohtsubo, Naoki Tokumasu +10
We fabricated spin-polarized surface electronic states with tunable Fermi level from semiconductor to low-dimensional metal in the Bi/GaSb(110)-(21) surface using angle-res…
Revealing electrically undetectable room temperature surface-mobility of bulky topological insulators by spectroscopic techniques
Bumjoo Lee, Jinsu Kim, Jonghyeon Kim +11
High surface-mobility, which is attributable to topological protection, is a trademark of three-dimensional topological insulators (3DTIs). Exploiting surface-mobility indicates su…
A minimal, "hydrogen atom" version of an inversion-breaking Weyl semimetal
Ilya Belopolski, Peng Yu, Daniel S. Sanchez +15
The recent explosion of research interest in Weyl semimetals has led to many proposed Weyl semimetal candidates and a few experimental observations of a Weyl semimetal in real mate…
Measuring Chern numbers above the Fermi level in the Type II Weyl semimetal MoWTe
Ilya Belopolski, Su-Yang Xu, Yukiaki Ishida +30
It has recently been proposed that electronic band structures in crystals give rise to a previously overlooked type of Weyl fermion, which violates Lorentz invariance and, conseque…
Electronic structure and relaxation dynamics in a superconducting topological material
Madhab Neupane, Yukiaki Ishida, Raman Sankar +9
Topological superconductors host new states of quantum matter which show a pairing gap in the bulk and gapless surface states providing a platform to realize Majorana fermions. Rec…
Gigantic surface life-time of an intrinsic topological insulator revealed via time-resolved (pump-probe) ARPES
Madhab Neupane, Su-Yang Xu, Yukiaki Ishida +11
The interaction between light and novel two-dimensional electronic states holds promise to realize new fundamental physics and optical devices. Here, we use pump-probe photoemissio…
Unexpectedly robust protection from backscattering in the topological insulator BiSbTeSe
Sunghun Kim, Shunsuke Yoshizawa, Yukiaki Ishida +5
Electron scattering in the topological surface state (TSS) of the bulk-insulating topological insulator BiSbTeSe was studied using quasiparticle int…
