Abstract

In this study, P-doped ZnO thin films were prepared on sapphire substrates by pulsed laser deposition and annealing method. The electrical properties were investigated as a function of annealing temperatures at a fixed oxygen pressure. The XRD measurement showed that p-doped ZnO thin films were c-axis oriented. The Hall measurement showed that p-type ZnO thin film was observed. The carrier concentration of $1.18{\times}10^{16}cm^{-3}$ and the mobility of $0.96\;cm^{-3}/Vs$ were obtained for the P-doped ZnO thin film fabricated annealing temperature $850^{\circ}C$.
