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…
Switching mechanism of photochromic diarylethene derivatives molecular junctions
Jing Huang, Qunxiang Li, Hao Ren +3
The electronic transport properties and switching mechanism of single photochromic diarylethene derivatives sandwiched between two gold surfaces with closed and open configurations…
Strain Effect on Energy Gaps of Armchair Graphene Nanoribbons
Lian Sun, Qunxiang Li, Hao Ren +3
We report a first-principles study on electronic structures of the deformed armchair graphene nanoribbons (AGNRs). The variation of the energy gap of AGNRs as a function of uniaxia…
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…
