Diamondization of Graphene and Graphene-BN Bilayers: Chemical Functionalization and Electronic Structure Engineering
Long Yuan, Zhenyu Li, Jinlong Yang +1
In this article, based on first-principles calculations, we systematically study functionalization induced diamonization of graphene bilayer and graphene-BN hybrid bilayer. With si…
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…
Coalescence of Carbon Atoms on Cu (111) Surface: Emergence of a Stable Bridging-Metal Structure Motif
Ping Wu, Wenhua Zhang, Zhenyu Li +2
By combining first principles transition state location and molecular dynamics simulation, we unambiguously identify a carbon atom approaching induced bridging metal structure form…
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…
How Graphene Is Cut upon Oxidation?
Zhenyu Li, * Wenhua Zhang, Yi Luo +3
Our first principles calculations reveal that oxidative cut of graphene is realized by forming epoxy and then carbonyl pairs. Direct forming carbonyl pair to tear graphene up from…
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 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…
