Spectromicroscopic measurement of surface and bulk band structure interplay in a disordered topological insulator
Erica Kotta, Lin Miao, Yishuai Xu +9
Topological insulators are bulk semiconductors that manifest in-gap massless Dirac surface states due to the topological bulk-boundary correspondence principle [1-3]. These surface…
Intrinsic superstructure near atomically clean armchair-type step edge of graphite
Wenhan Zhang, Zheng Ju, Weida Wu
We investigated the electronic superstructure of graphite surface in the vicinity to monoatomic armchair step edges with scanning tunneling microscopy and spectroscopy. Only the ($…
Electronic Fingerprints of Cr and V Dopants in Topological Insulator Sb2Te3
Wenhan Zhang, Damien West, Seng Huat Lee +6
By combining scanning tunneling microscopy/spectroscopy and first-principles calculations, we systematically study the local electronic states of magnetic dopants V and Cr in the t…
Observation of a Topological Insulator Dirac Cone Reshaped by Non-magnetic Impurity Resonance
Lin Miao, Yishuai Xu, Wenhan Zhang +10
The massless Dirac electrons found at topological insulator surfaces are thought to be influenced very little by weak, non-magnetic disorder. However, a resonance effect of strongl…
Topological phase transition with nanoscale inhomogeneity in (BiIn)Se
Wenhan Zhang, M. X. Chen, Jixia Dai +4
Topological insulators are a class of band insulators with non-trivial topology, a result of band inversion due to the strong spin-orbit coupling. The transition between topologica…
Solution to the hole-doping problem and tunable quantum Hall effect in BiSe thin films
Jisoo Moon, Nikesh Koirala, Maryam Salehi +3
BiSe, one of the most widely studied topological insulators (TIs), is naturally electron-doped due to n-type native defects. However, many years of efforts to achieve p…
