Study the structural properties of Au thin film deposited on poly vinyl alcohol prepared by plasma sputtering method

Abstract EN

In this research, preparation of Au films on poly vinyl alcohol (PVA) substrates by using plasma direct current glow discharge sputtering (FT-IR)results for poly vinyl alcohol showed matching the sites of the active groups of the polymer with its chemical composition X-ray diffraction (XRD) showed that the thin films had a polycrystalline while the surface roughness was diagnosed using an atomic force microscopy (AFM)the where the results showed that the roughness increased from (30.099-55.221)nm with increasing the thickness from (90-195)nm.

scanning electron microscope(SEM)showed that nanoparticles with a spherical shape the particles aggregates to form larger clusters with increased film thickness.
