Al-N codoped p-type ZnO thin films have been prepared by DC magnetron reactive sputtering reproducibly using a high-temperature (HT) homo-buffer layer. The influence of HT buffer layer deposition time (Tht) on film properties was investigated by X-ray diffraction (XRD), scanning electron micro-spectra (SEM) and Hall measurement. The Al-N codoped ZnO film was improved evidently in its crystal quality by varying the value of Tht. Results of Hall effect showed that all of the Al-N codoped ZnO thin films were p-type conduction and had resistivity mainly below 50 Ω cm. The optimum deposition time of HT buffer layer is around 3 min from the comprehensive consideration of structural, electrical, and optical properties. The obtained ZnO thin film can meet the need of application in optoelectronic devices based on ZnO.
