Engineering Dirac electrons emergent on the surface of a topological insulator
Yukinori Yoshimura, Koji Kobayashi, Tomi Ohtsuki +1
The concept of topological insulator (TI) has introduced a new point of view to condensed-matter physics, relating a priori unrelated subfields such as quantum (spin, anomalous) Ha…
Modification and Control of Topological Insulator Surface States Using Surface Disorder
Vincent Sacksteder, Tomi Ohtsuki, Koji Kobayashi
We numerically demonstrate a practical means of systematically controlling topological transport on the surface of a three dimensional topological insulator, by introducing strong…
Dimensional crossover of transport characteristics in topological insulator nanofilms
Koji Kobayashi, Yukinori Yoshimura, Ken-Ichiro Imura +1
We show how the two-dimensional (2D) topological insulator evolves, by stacking, into a strong or weak topological insulator with different topological indices, proposing a new con…
