The Electrical Properties of Al/Methylene-Blue/n-Si/Au Schottky Diodes

Abstract

We studied the electrical characteristics of Al/methylene-blue/n-Si/Au Schottky diodes such as current-voltage, conductance-capacitance-voltage, and conductance-capacitance-frequency. We plotted rectification ratio vs. voltage (RR-V) of the diode. From I-V plots of the diodes, saturation current (Io), and ideality factor (n) were calculated. Barrier height (eFB) and series resistance (RS) were calculated with Norde functions. The results show that in the Al/methylene-blue/n-Si/Au diode, the methylene-blue layer has a significant impact on electrical properties such as series resistance, barrier height, ideality factor, conductance, rectification ratio, and capacitance.
