Fabrication and Study of P-Type ZnO Films by RF Magnetron Sputtering of ZnO: In2O3 Powder Together with the N-Implantation

Article Preview

Abstract:

The N-In codoped p-type ZnO films with preferential orientation along (002) plane have been fabricated on quartz glass substrates using radio frequency magnetron sputtering technique of ZnO:In2O3 powder target combining with N-implantation. The samples annealed at 700°C deserved the optimal properties, the best of which exhibits electrical characteristics with the hole concentration of 4.04×1018 cm-3, the lowest resistivity of 1.15 Ωcm and Hall mobility of about 1.35 cm2V-1s-1. The effects of post-annealing on the microstructure and electronic properties of the codoped ZnO films is analyzed via SEM, XRD, XPS and Hall measurements system, and the trend of carrier concentration with annealing time is discussed theoretically.
