|
The quantum tunnelling of spin-polarized electrons through a Rashba barrier on a single layer graphene is
studied by the scattering matrix method. It is shown that the magnetoresistance, defined as the difference between
conductance at the presence and absence of the Rashba spin–orbit interaction, oscillates with the intensity of
interaction. These oscillations are also observed in the conductance versus the potential energy of the barrier.
