Quasiparticle and Transport Properties of Disordered Bilayer Graphene
Yanru Chen, Bo Fu, Jinrong Xu +3
In recent experimental and theoretical studies of graphene, disorder scattering processes have been suggested to play an important role in its electronic and transport properties.…
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…
On the sample-dependent minimal conductivity in weakly disordered graphene
Weiwei Chen, Yedi Shen, Bo Fu +2
We present a unified understanding of the experimentally observed minimal dc conductivity in weakly disordered graphene. Firstly, based on linear response theory, we reveal that ra…
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 …
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…
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…
Analytical Study of Electronic Structure in Armchair Graphene Nanoribbons
Huaixiu Zheng, Zhengfei Wang, Tao Luo +2
We present the analytical solution of the wavefunction and energy dispersion of armchair graphene nanoribbons (GNRs) based on the tight-binding approximation. By imposing hard-wall…
