In this paper, the morphology, roughness and nano structural properties of SiO2/Poly Vinyl Pyrrolidone  synthesized with sol gel method,  characterized by using scanning electron microscopy, atomic force microscopy and GPS132A techniques.The main material taken from oxide silicon with weight percentage of 20, 40, 60, 80 and from poly vinyl pyrrolidone with percentages of 80, 60, 40, 20 is synthesized and are called sample 1, 2, 3 and 4 respectively. The samples usinglower poly vinyl pyrrolidone  (PVP:SiO2; 2:3 in Weight) can be suitable  choices in producing organic field-effect transistors due to their better structuralquality, less energy loss, less roughness sample surface, higher dielectric constant (K=15.99 )  and better surface morphology as determined with applying DME SPM software and above techniques. This sample can be thus considered as a good element of the future organic field-effect transistors devices.
