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…
