Abstract

A graphene p - n junction is studied theoretically in the presence of both intrinsic and extrinsic (Rashba) spin-orbit interactions. It is shown that a crossover from perfect reflection to perfect transmission is achieved at normal incidence by tuning the perpendicular electric field. We also study angular-dependent transmission for demonstrating that perfect reflection at normal incidence can be clearly distinguished from trivial band gap effects. We clarify how spin-orbit effects modify the conductance and the Fano factor associated with a potential step in both nn and np cases.
