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…
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 …
