Reactively sputtered MoO3 thin films and temperature dependence of electrical properties of an Ag/MoO3/n-Si Diode

Abstract

MoO3 thin films were deposited onto n-Si and soda lime glass substrates by the reactive sputtering method. The influence of reactive gas flows on the morphological, structural and optical properties of thin films were analyzed by Atomic Force Microscopy (AFM), X-ray Diffraction (XRD) system and UV-Vis data. It was seen that the homogeneity and amorphousness of the films increase with the O2 ratio. In addition, the Ag/MoO3/n-Si structure was obtained by evaporation of Ag on MoO3/n-Si structure. It was seen that the device had excellent rectification. The electrical properties of Ag/MoO3/n-Si structure were analyzed by current-voltage (I-V) measurements in the dark between 77 and 500 K. It was reported that the temperature had a strong influence on the electrical parameters of the device. © 2018, S.C. Virtual Company of Phisics S.R.L. All rights reserved.
