Electrical properties of NiO/PVC nano hybrid composites for organic field effect transistors

Abstract

In this study, NiO/PVC nano hybrid composites have been synthesized through sol–gel method. Nano crystallites phases, crystallinity and electrical properties have been characterized using X-ray diffraction, Fourier transfer infrared radiation, scanning electron microscopy and atomic force microscopy techniques. The dielectric constant of the samples has been calculated through measuring the capacity of samples by application of GPS 132 A. Obtained results have indicated that an NiO/PVC sample with 5 g NiO and 0.02 g PVC, equivalent to 0.4 %wt PVC, in weight synthesis, at a temperature of 80 °C has a higher dielectric constant, better surface morphology, less rough surface, less leakage current, and thus has potential to be suggested as a possible gate dielectric material for future organic field effect transistor devices.
