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…
Topological phase transition in Dirac fermionic heterostructures
Jeongwoo Kim, Jinwoong Kim, Ki-Seok Kim +1
Materials with non-trivial topology in their electronic structures enforce the existence of helical Dirac fermionic surface states. We discovered emergent topological phases in the…
Topological insulating behaviour in conducting property of crystalline Ge-Sb-Te
Jeongwoo Kim, Jinwoong Kim, Seung-Hoon Jhi
We report a discovery, through first-principles calculations, that crystalline Ge-Sb-Te (GST) phase-change materials exhibit the topological insulating property. Our calculations s…
