Abstract

Al:ZnO thin films were deposited using the radio frequency magnetron sputtering technique at various temperatures and sputtering powers. With the increase in the deposition temperature and the decrease in the radio frequency sputtering power, the crystallinity was increased and the surface roughness was decreased, which lead to the decrease in the electrical resistivity of the film. It is also clearly observed that, the intensity of the (002) XRD peak increases with increasing the substrate temperature [1,2]. The electrical resistivity and optical transmittance of the Al:ZnO thin film were analyzed as a function of the post-annealing temperature. It can be seen that with the annealing temperature set at $400^{\circ}C$, the resistivity decreases to a minimum value of $4.1{\times}10^{-3}{\Omega}cm$ and the transmittance increases to a maximum value of 85% of the Al:ZnO thin film.
