Topological surface states of Bi2Se3 with the coexistence of Se vacancies
Binghai Yan, Delin Zhang, Claudia Felser
Although topological surface states are known to be robust against non-magnetic surface perturbations, their band dispersions and spatial distributions are still sensitive to the s…
Prediction of weak topological insulators in layered semiconductors
Binghai Yan, Lukas Muechler, Claudia Felser
We report the discovery of weak topological insulators by ab initio calculations in a honeycomb lattice. We propose a structure with an odd number of layers in the primitive unit-c…
Theoretical prediction of topological insulator in ternary rare earth chalcogenides
Binghai Yan, Hai-Jun Zhang, Chao-Xing Liu +3
A new class of three-dimensional topological insulator, ternary rare earth chalcogenides, is theoretically investigated with ab initio calculations. Based on both bulk band structu…
