Spin-related tunneling through a nanostructured electric-magnetic barrier on the surface of a topological insulator
We investigate quantum tunneling through a single electric and/or magnetic barrier on the surface of a three-dimensional topological insulator. We found that (1) the propagating behavior of electrons in such system exhibits a strong dependence on the direction of the incident electron wavevector and...
