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...

| 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 occurs for end-bonded contacts due to the geometry variation in the case of Schottky Au-ZnO nanowire interfaces. The change in the geometry will also lead to a change in the electrical behavior of the contact from Schottky to Ohmic which can substantially reduce the contact resistance. |
