Dirac semimetal phase in the hexagonal LiZnBi
Wendong Cao, Peizhe Tang, Yong Xu +3
Based on first-principles calculations, we find that LiZnBi, a metallic hexagonal compound, can be driven into a Dirac semimetal with a pair of Dirac points by strain. The no…

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 Dirac semi-metal in the allotrope of IV elements
Wendong Cao, Peizhe Tang, Shou-Cheng Zhang +2
Three dimensional topological Dirac semi-metals represent a novel state of quantum matter with exotic electronic properties, in which a pair of Dirac points with the linear dispers…
