Nanoscale diode, molecular rectifier, tight-binding model, conductance, current


In this study, Nano-diode is proposed using an asymmetric structure of two different molecules attached to metal electrodes. The asymmetric molecular structure acts as a molecular diode (MD) in uniformity circuits at the Nano scale. A tight-binding model is adopted to describe MD, and the results are based on the steady-state formula to illustrate charge transfer. Theoretical calculations of the conductivity and current as a function of time, the study of the effect of heat on it, as well as the study of the rectification current ratio as a function of bias voltage, all these calculations were made using two types of molecules of DNA, they are (G/C) and (A/T). The results were encouraging because they gave the common features of the rectification. The analysis may be useful in the fabrication of electronic devices with Nanotechnology.
