| Electronic transport in a graphene junction is considered theoretically. Graphene is assumed to be deposited on a substrate which generates Rashba spin-orbit coupling. However, the Rashba parameters in the two parts of the junction are assumed to be generally different. Additionally, different gate voltages are applied to the two parts, which allow tuning the Fermi level and potential step. We analyze the probabilities of electron transmission through the junction and electrical conductance in the linear response regime. |
