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…

Experimental observation of Dirac-like surface states and topological phase transition in PbSnTe(111) films
Chenhui Yan, Junwei Liu, Yunyi Zang +12
The surface of a topological crystalline insulator (TCI) carries an even number of Dirac cones protected by crystalline symmetry. We epitaxially grew high quality PbSnT…

Functionalized Germanene as a Prototype of Large-Gap Two-Dimensional Topological Insulators
Chen Si, Junwei Liu, Yong Xu +3
We propose new two-dimensional (2D) topological insulators (TIs) in functionalized germanenes (GeX, X=H, F, Cl, Br or I) using first-principles calculations. We find GeI is a 2D TI…
