Vacancy Induced Splitting of Dirac Nodal Point in Graphene
W. Zhu, W. Li, Q. W. Shi +4
We investigate the vacancy effects on quasiparticle band structure of graphene near the Dirac point. It is found that each Dirac nodal point splits into two new nodal points due to…
Accurate evaluation of the Green's function of disordered graphenes
W. Zhu, Q. W. Shi, X. R. Wang +4
An accurate simulation of Green's function and self-energy function of non-interacting electrons in disordered graphenes are performed. Fundamental physical quantities such as the…
The shape of disorder broadened Landau subbands in graphene
W. Zhu, Q. W. Shi, X. R. Wang +2
Density of states (DOS) of graphene under a high uniform magnetic field and white-noise random potential is numerically calculated. The disorder broadened zero-energy Landau band h…
Electronic Structure in Gapped Graphene with Coulomb Potential
W. Zhu, M. L. Liang, Q. W. Shi +3
In this paper, we numerically study the bound electron states induced by long range Coulomb impurity in gapped graphene and the quasi-bound states in supercritical region based on…
