Charge and spin transport across two-dimensional non-centrosymmetric semiconductor/metal interface

► We calculated conductance at zero voltage of metal/Rashba system junction. ► It exhibits a kink that occurs when Fermi level coincides with the intersection of Rashba bands. ► In two transparency limits, the dependences of the conductance on the Rashba spin-orbit coupling strength are different. ► The polarization of current in the metal is different from that in the Rashba system.
