Thickness Dependence of Structural and Optical Properties of Al/ZnO Films Prepared by DC Magnetron Sputtering

Article Preview

Abstract:

In this paper, AZO thin films of different thicknesses were deposited on glass substrates as transparent conducting (TCO) films by changing the deposition time using a DC magnetron sputtering method. The effect of film thicknesses on the structural and optical properties of AZO films was investigated using X-ray diffractometer (XRD) and spectrophotometer, respectively. Results show that increasing the film thickness results in decreasing the optical transmittance. The optimum properties were obtained for a film with 500 nm thickness and 90 min deposition time, which exhibited a transmittance of 95%.
