Theoretical study on quantum transport phenomena originating from unusual electronic states

点击翻译按钮获取中文摘要

Quantum transport phenomena due to the massless Dirac particles have been studied in semiconductors with spin-orbit interaction and graphene. In the former case, non-zero spin-Hall conductance survives for a finite system with contacts for any impurity density. In the latter, peculiar conduction is given for systems of low impurity density, while Anderson localization takes place for high impurity density as is the case with normal two-dimensional electronic systems.
