Rippled Graphene as an Ideal Spin Inverter

We analyze a ballistic electron transport through a corrugated (rippled) graphene system with a curvature-induced spin-orbit interaction. The corrugated system is connected from both sides to two flat graphene sheets. The rippled structure unit is modeled by upward and downward curved surfaces. The cooperative effect of N units connected together (the superlattice) on the transmission of electrons that incident at the arbitrary angles on the superlattice is considered. The set of optimal angles and corresponding numbers of N units that yield the robust spin inverter phenomenon are found.
