Ultra-low carrier concentration and surface dominant transport in Sb-doped Bi2Se3 topological insulator nanoribbons
Seung Sae Hong, Judy J. Cha, Desheng Kong +1
A topological insulator is a new state of matter, possessing gapless spin-locking surface states across the bulk band gap which has created new opportunities from novel electronics…
Ambipolar Field Effect in Topological Insulator Nanoplates of (BixSb1-x)2Te3
Desheng Kong, Yulin Chen, Judy J. Cha +11
Topological insulators represent a new state of quantum matter attractive to both fundamental physics and technological applications such as spintronics and quantum information pro…
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…
