Growth of 2D topological material Bi on InSb(111)B with fractal surface structures
Yoshiyuki Ohtsubo, Takuto Nakamura, Shin-ichi Kimura
Bismuth (Bi) atomic layers are known as 2D topological materials with variety of the electronic structures and topological orders depending on the number of stacking layers. Recent…
Surface valence transition in SmS by alkali metal adsorption
Takuto Nakamura, Toru Nakaya, Yoshiyuki Ohtsubo +9
The electronic structure changes of SmS surfaces under potassium (K) doping are elucidated using synchrotron-based core-level photoelectron spectroscopy and angle-resolved photoele…
Breakdown of bulk-projected isotropy in surface electronic states of topological Kondo insulator SmB(001)
Yoshiyuki Ohtsubo, Toru Nakaya, Takuto Nakamura +4
The topology and spin-orbital polarization of two-dimensional (2D) surface electronic states have been extensively studied in this decade. One major interest in them is their close…
