Abstract

For the first time, the polyvinyl alcohol: graphene oxide nanocomposite films for various contents of graphene oxide nanosheets were prepared by spin coating method. The synthesized GO nanosheets and PVA/GO nanocomposites were characterized using field emission scanning electron microscope (FETEM) technique and energy dispersive X-ray spectroscopy (EDS). The electrical conductivity and current-voltage characteristics of PVA/GO nanocomposites were investigated. The nanocomposites were underwent a transition from insulator to semiconductor behavior with GO content. The electrical characterization of Al/PVAGO/p-Si/Au diode was investigated by means of current-voltage and capacitance-voltage measurements. The prepared Al/PVAGO/p-Si/Au diodes exhibited the rectifying behavior and the rectifying properties were changed with GO content. Considering the very simple and effective fabricate process, the Al/PVAGO/p-Si/Au diodes are competitive candidate for several electronic applications.
