Disorder Effects on the Quasiparticle and Transport Properties of Two-Dimensional Dirac Fermionic Systems
Bo Fu, Yanru Chen, Weiwei Chen +5
Despite extensive existing studies, a complete understanding of the role of disorder in affecting the physical properties of two-dimensional Dirac fermionic systems remains a stand…
Spin-orbit related power-law dependence of the diffusive conductivity on the carrier density in disordered Rashba two-dimensional electron systems
Weiwei Chen, Cong Xiao, Qinwei Shi +1
By using the momentum-space Lanczos recursive method which considers rigorously all multiple-scattering events, we unveil that the non-perturbative disorder effect has dramatic imp…
Unusual Metal to Marginal-Metal Transition in Two-Dimensional Ferromagnetic Electron Gases
Weiwei Chen, C. Wang, Qinwei Shi +2
Two-dimensional ferromagnetic electron gases subject to random scalar potentials and Rashba spin-orbit interactions exhibit a striking quantum criticality. As disorder strength …
Tunable band gap of graphane nanoribbons under uniaxial elastic strain: a first-principles study
Yan Zhang, Xiaojun Wu, Qunxiang Li +1
In this Letter, we investigate the strain-induced band-gap modulation of both armchair and zigzag graphane nanoribbons based on the first-principles calculations. Within the elasti…
Electronic Structures of SiC Nanoribbons
Lian Sun, Yafei Li, Zhenyu Li +5
Electronic structures of SiC nanoribbons have been studied by spin-polarized density functional calculations. The armchair nanoribbons are nonmagnetic semiconductor, while the zigz…
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…
