Abstract

In this research, aluminum zinc oxide nanostructure thin films of various thickness (200, 250, 300 nm) were deposited on polycarbonate polymer substrates using a magnetron sputtering technique. The properties of the thin films were investigated by X-ray diffraction, Field Emission Scanning Electron Microscopy, X-ray Photoelectron Spectroscopy, UV-VIS-NIR spectrophotometer and four point probe method. X-ray diffraction pattern showed that the aluminum zinc oxide thin film included polycrystalline structure. The morphological results indicated that grain size increased as the thickness increased. The transmittance and sheet resistance of the aluminum zinc oxide thin films showed that aluminum zinc oxide thin films with 200 nm thickness had the highest transmission whereas aluminum zinc oxide thin film with 300 nm had the best conductivity..
