A topological crystalline insulator (TCI) phase via topological phase transition and crystalline mirror symmetry
Su-Yang Xu, Chang Liu, Nasser Alidoust +18
A Z2 topological insulator protected by time-reversal symmetry is realized via spin-orbit interaction driven band inversion. For example, the topological phase in the Bi-Sb system…

Observation of Topological Crystalline Insulator phase in the lead tin chalcogenide Pb1-xSnxTe material class
Su-Yang Xu, Chang Liu, N. Alidoust +11
We perform systematic angle-resolved photoemission spectroscopic measurements on the lead tin telluride Pb1-xSnxTe pseudobinary alloy system. We show that the (001) crystalline sur…
