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…
Average Density of States in Disordered Graphene systems
Shangduan Wu, Lei Jing, Qunxiang Li +4
In this paper, the average density of states (ADOS) with a binary alloy disorder in disordered graphene systems are calculated based on the recursion method. We observe an obvious…
Quantum Dot in Z-shaped Graphene Nanoribbon
Z. F. Wang, Huaixiu Zheng, Q. W. Shi +3
Stimulated by recent advances in isolating graphene, we discovered that quantum dot can be trapped in Z-shaped graphene nanoribbon junciton. The topological structure of the juncti…
Electronic Structure of Bilayer Graphene: A Real-space Green's Function Study
Z. F. Wang, Qunxiang Li, Haibin Su +5
In this paper, a real-space analytical expression for the free Green's function (propagator) of bilayer graphene is derived based on the effective-mass approximation. Green's funct…
Graphene switch design: an illustration of the Klein paradox
Q. W. Shi, Z. F. Wang, Jie Chen +5
An armchair graphene ribbon switch has been designed based on the principle of the Klein paradox. The resulting switch displays an excellent on-off ratio performance. Anomalous tun…
