Abstract:High quality c axis oriented single crystal ZnO films have been successfully grown on the (0002) sapphire substrates by Low Pressure MOCVD using Zn(C 2H 5) 2 and CO 2 as sources.The crystallinity and the orientation of the films were studied by X ray diffraction technique.The lattice constant for the ZnO film on the sapphire substrate is 0.5218 nm,which is a bit higher than the reported value in ZnO film.The optical band gap is about 3.245 eV by simulating the data of the absorption spectrum.The edge emission band has been observed obviously in the PL spectrum and the origin of the blue emission band has been also revealed and discussed.
Keywords:ZnO  metal organic chemical vapor deposition(MOCVD)  X  ray diffraction  photoluminescence  absorption
