Abstract

Nanoscale electron tunneling and thermionic transport via the metal-semiconductor interface of ZnO nanowires is found to be strongly affected by the metal contact shape, the metal-semiconductor interface radius and the nanowire radius. Our full 3D simulations show that the current crowding effect oc...
