p-type ZnO thin films have been realized via co-doping of In and N by using dc reactive magnetron sputtering method. X-ray diffraction (XRD) measurement showed that all films possessed a good crystallinity with
c
-axis preferential orientation. The lowest reliable room-temperature resistivity was found to be 35.6 Ω·cm with carrier concentration of 1.57×10

. X-ray photo-electron spectroscopy confirms that In had been incorporated into the ZnO films effectively and the presence of In enhanced the incorporation of N. The transmittance spectrum revealed that the transmittance of all films was about 90% in the visible region.
