Abstract
Nitrogen-doped ZnO (ZnO:N) films are prepared by thermal oxidation of sputtered Zn3N2 layers on Al2O3 substrate.The dependence of the structural and optical properties of the ZnO:N films on annealing temperature is investigated.X-ray Diffraction (XRD) results illustrate that the as-sputtered Zn3N2 films can be transformed into ZnO:N films after annealing at 600℃ and above.X-ray photoelectron spectroscopy (XPS) reveals that nitrogen has two chemical states in the ZnO:N films:(N2)o and No,which denote substitution of molecular N for O and atomic N for O,respectively.Hall effect measurements illustrate that the hole concentration in ZnO:N films annealed at 700℃ is the highest.The FA and DAP transition peaks are observed in low temperature photoluminescence spectra,from which the nitrogen acceptor binding energy can be obtained.-
