Atomically Abrupt Topological p-n Junction
Sung Hwan Kim, Kyung-Hwan Jin, Byung Woo Kho +4
Topological insulators (TI's) are a new class of quantum matter with extraordinary surface electronic states, which bear great potential for spintronics and error-tolerant quantum…
Topological phase transition and quantum spin Hall edge states of antimony few layers
Sung Hwan Kim, Kyung-Hwan Jin, Joonbum Park +3
While two-dimensional topological insulators (2D TI) initiated the field of topological materials, only very few materials were discovered to date and the direct access to their qu…
Transforming a Surface State of Topological Insulator by a Bi Capping Layer
Han Woong Yeom, Sung Hwan Kim, Woo Jong Shin +7
We introduce a dinstint approach to engineer a topologically protected surface state of a topological insulator. By covering the surface of a topological insulator, Bi2Te2Se, with…
Edge and Interfacial States in a 2D Topological Insulator:Bi(111) Bilayer on BiTeSe
Sung Hwan Kim, Kyung-Hwan Jin, Joonbum Park +4
The electronic states of a single Bi(111) bilayer and its edges, suggested as a two dimensional topological insulator, are investigated by scanning tunneling spectroscopy (STS) and…
