Abstract

In this studying, a nanoscale diode was proposing by using asymmetric double quantum dot structure attached to metallic electrodes. An asymmetric double quantum dot (ADQD) is used as a diode for rectification. Tight-binding model was adopting to describe our specimen, and our results depend upon steady-state forming to show charge transport. The theoretical computations for current and conductance as a function of the time, that encouraging common traits of the rectifications, were presented. The analysis may be helpful in fabricating nanoscale electronic devices.
