Topological phase diagram and saddle point singularity in a tunable topological crystalline insulator
Madhab Neupane, Su-Yang Xu, R. Sankar +17
We report the evolution of the surface electronic structure and surface material properties of a topological crystalline insulator (TCI) Pb1-xSnxSe as a function of various materia…
Saddle point singularity and topological phase diagram in a tunable topological crystalline insulator (TCI)
Madhab Neupane, Su-Yang Xu, R. Sankar +15
A topological crystalline insulator (TCI) is a new phase of topological matter, which is predicted to exhibit distinct topological quantum phenomena, since space group symmetries r…
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…
