Heavy Dirac fermions in a graphene/topological insulator hetero-junction
Wendong Cao, Rui-Xing Zhang, Peizhe Tang +4
The low energy physics of both graphene and surface states of three-dimensional topological insulators is described by gapless Dirac fermions with linear dispersion. In this work,…

Stable two-dimensional dumbbell stanene: a quantum spin Hall insulator
Peizhe Tang, Pengcheng Chen, Wendong Cao +7
We predict from first-principles calculations a novel structure of stanene with dumbbell units (DB), and show that it is a two-dimensional topological insulator with inverted band…
