We analyse spin scattering in ballistic transport of electrons through a ripple at a normal incidence of an electron flow. The model of a ripple consists of a curved graphene surface in a form of arc of a circle connected from the left-hand and the right-hand sides to two flat graphene sheets. At certain conditions the curvature induced spin-orbit coupling creates a transparent window for incoming electrons with one spin polarization simultaneously with a backscattering of those with an opposite polarization. This window is equally likely transparent for electrons with spin up and spin down that move in the opposite directions. |
