Converting normal insulators into topological insulators via tuning orbital levels
Wu-Jun Shi, Junwei Liu, Yong Xu +3
Tuning the spin-orbit coupling strength via foreign element doping and/or modifying bonding strength via strain engineering are the major routes to convert normal insulators to top…
Large-Gap Quantum Spin Hall States in Stanene Grown on Substrate
Yong Xu, Peizhe Tang, Shou-Cheng Zhang
Two-dimensional stanene is a promising candidate material for realizing room-temperature quantum spin Hall (QSH) effect. Monolayer stanene has recently been fabricated by molecular…
Epitaxial Growth of Two-Dimensional Stanene
Fengfeng Zhu, Wei-jiong Chen, Yong Xu +6
Ultrathin semiconductors present various novel electronic properties. The first experimental realized two-dimensional (2D) material is graphene. Searching 2D materials with heavy e…
Effects of ferroelectric polarization on surface phase diagram: an evolutionary algorithm study of the BaTiO(001) surface
Pengcheng Chen, Yong Xu, Na Wang +2
We have constructed the surface phase diagram of the BaTiO(001) surface by employing an evolutionary algorithm for surface structure prediction, where the ferroelectric polar…
Disentangling the magnetoelectric and thermoelectric transport in topological insulator thin films
Jinsong Zhang, Xiao Feng, Yong Xu +14
We report transport studies on (Bi,Sb)2Te3 topological insulator thin films with tunable electronic band structure. We find a doping and temperature regime in which the Hall coeffi…
