Single-parameter quantum valley pumping in graphene with topological line defect
We report a theoretical study of single-parameter quantum valley pumping in graphene with a topological line defect via the Keldysh Green’s function method. It is found that the valley pumping currents appear only at large scattering angles, with the negative sign for K valley while positive sign fo...
