Rapid Surface Oxidation as a Source of Surface Degradation Factor for Bi2Se3
Desheng Kong, Judy J. Cha, Keji Lai +8
Bi2Se3 is a topological insulator with metallic surface states residing in a large bulk bandgap. It is believed that Bi2Se3 gets additional n-type doping after exposure to atmosphe…
Topological Insulators in Ternary Compounds with a Honeycomb Lattice
Hai-Jun Zhang, Stanislav Chadov, Lukas Müchler +5
One of the most exciting subjects in solid state physics is a single layer of graphite which exhibits a variety of unconventional novel properties. The key feature of its electroni…
Electronic Structures and Surface States of Topological Insulator BiSb
Hai-Jun Zhang, Chao-Xing Liu, Xiao-Liang Qi +4
We investigate the electronic structures of the alloyed BiSb compounds based on first-principle calculations including spin-orbit coupling (SOC), and calculate the surf…
Enhanced Orbital Degeneracy in Momentum Space for LaOFeAs
Hai-Jun Zhang, Gang Xu, Xi Dai +1
The Fermi surfaces (FS) of LaOFeAs (in =0 plane) consist of two hole-type circles around point, which do not touch each other, and two electron-type co-centered ellipses a…
