Graphene oxide (GO) belongs to carbon family with honeycomb structure having hydroxide, carbonyl, and carboxylic moieties at its basal plane. These functionalities are decreased in reduced graphene oxide (rGO), and this boosts the intrinsic properties of GO. Herein, in this work, the effect on physical and chemical properties of GO and rGO in combination with copper-doped zinc oxide (Cu–ZnO) thin films, prepared via DC/RF sputtering, was investigated for the very first time. The deposition of Cu–ZnO over rGO (Cu–ZnO@ rGO) showed remarkably superior properties and presented an extension in d-spacing without preferred plane orientation of Cu–ZnO plane, and this was found to be due to its hydrophobic nature. The decrease in band gap of composite thin films was due to the surface electric charge conducted by GO or rGO. The enhanced dielectric constant is attributed due to increase in electron–hole pairs …
