Abstract
The experimental and theoretical realization of 10% graphene doped ZnO/Graphene thin film alcohol sensor has been reported. The alcohol sensor has been fabricated by sol-gel method and theoretically verified by DFT-based first principle calculations. The quality of the fabricated device has been studied using SEM and UV measurements. To determine its figures-of-merit, the conductivity, transfer characteristics, and response measurements have been analyzed. In addition, the device has undergone three different exposures of alcohol concentrations such as Brandy, Whiskey, and Rum with varying exposure times.
