Analysis of the Current-Voltage Hysteresis Behavior of Polyvinyl Alcohol-Zinc selenide Nanocomposite Film

Abstract

Abstract The temperature dependent current-voltage characteristics of the Polyvinyl Alcohol-Zinc selenide nanocomposite films were studied in the voltage window of -5V to +5V. It was observed that with the increase in applied voltage and temperature, the current-voltage characteristics shift from ohmic to non-ohmic nature and show hysteresis behavior. It has also been observed that the sample resistance changes from low resistance state (LRS) to high resistance state (HRS) depending on the applied voltage and temperature. The observed phenomenon has been analyzed based on the available theoretical models to elucidate the prevailing current conduction mechanism.
