Abstract :
ZnO films were grown by metal-organic chemical vapor deposition (MOCVD) on sapphire and Si substrate. Thermal annealing was performed on ZnO thin films deposited on Si substrate. X-ray diffraction spectra indicated that all ZnO films were strongly c-oriented. Strong ultraviolet (UV) emission was observed. X-ray photoelectron spectroscopy (XPS) measurements were performed to confirm the stoichiometry of ZnO film. Optical pumped UV lasing was obtained at room temperature. N-doped ZnO samples were realized by ionizing N2 and NH3. High resistive ZnO films were obtained by N-doping.
