Dirac Fermions in Antiferromagnetic Semimetal
Peizhe Tang, Quan Zhou, Gang Xu +1
The analogues of elementary particles have been extensively searched for in condensed matter systems because of both scientific interests and technological applications. Recently m…
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…
