Thin films of ZnO were deposited on cleaned soda lime glass substrates by using RF magnetron sputtering technique for deposition time of 20mins, 40mins, 60mins, 80mins and 100mins at room temperature. The structural and electrical properties of ZnO thin films were obtained from X-ray diffraction (XRD), Atomic force microscopy (AFM) and Hall Effect measurement. XRD results confirm the presence of (002) crystal orientation of ZnO and improvement of grain size was observed for films with higher deposition time. The average and the R.M.S roughness have been measured from the AFM images and the Hall Effect measurement confirms the carrier concentration, resistivity and mobility. Hall Effect data revealed that the mobility of the carriers of ZnO thin films increased with higher deposition time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
