Band gap anomaly and topological properties in lead chalcogenides

Simin Nie, Xiao Yan Xu, Gang Xu +1

Band gap anomaly is a well-known issue in lead chalcogenides PbX (X=S, Se, Te, Po). Combining ab initio calculations and tight-binding (TB) method, we have studied the band evoluti…

Topological nature of FeSe $_{0.5}$ Te $_{0.5}$ superconductor

Zhijun Wang, P. Zhang, Gang Xu +10

We demonstrate, using first-principles calculations, that the electronic structure of FeSe $_{1 - x}$ Te $_{x}$ ( $x$ =0.5) is topologically non-trivial, characterized by an odd $\mathbb…
