Absence of a supercritical regime induced by short-range impurity scattering in gapped graphene
Stepan Grinek, Zhou Li, Jie Chen +2
We show that the changes in the electronic density of states (DOS) in graphene induced by impurity scattering with short-range potentials are completely different from those caused…
Edge Effects on the Electronic Structures of Chemically Modified Armchair Graphene Nanoribbons
Hao Ren, Qunxiang Li, Haibin Su +3
In this paper, we apply the first-principle theory to explore how the electronic structures of armchair graphene nanoribbons (AGNRs) are affected by chemical modifications. The edg…
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…
Tuning the electronic structures of armchair graphene nanoribbons through chemical edge modification: A theoretical study
Z. F. Wang, Qunxiang Li. Huaixiu Zheng, Hao Ren +3
We report combined first-principle and tight-binding (TB) calculations to simulate the effects of chemical edge modifications on structural and electronic properties. The C-C bond…
An insight into the electronic structure of graphene: from monolayer to multi-layer
Z. F. Wang, Huaixiu Zheng, Q. W. Shi +3
In this paper, we analytically investigate the electronic structure of Bernal stacking (AB stacking) graphene evolving from monolayer (a zero-gap semiconductor with a linear Dirac-…
