Electron transport in self-switching nano-diodes

摘要

By using a two dimensional ensemble Monte-Carlo (2D EMC) method, the behavior of electrons transporting through asymmetric nano-wires, referred to as self-switching nano-diodes (SSDs), is studied. Our numerical results show that the diode-like characteristic is an intrinsic property of the geometric asymmetry in the nanometer scale and the surface states originated from the fabricating processes results in the presence of the threshold voltages.
