摘 要: | ZnO films were deposited by low-pressure metal organic chemical vapour deposition on epi-GaN/Al203 films and c-Al203 substrates. The structure and optical properties of the ZnO/GaN/Al203 and ZnO/Al203 films have been investigated to determine the differences between the two substrates. ZnO films on GaN/Al203 show very strong emission features associated with exciton transitions, just as ZnO films on Al2O3, while the crystalline structural qualities for ZnO films on GaN/Al2O3 are much better than those for ZnO films directly grown on Al203 substrates. Zn and O elements in the deposited ZnO/GaN/Al2O3 and ZnO/Al2O3 films are investigated and compared by x-ray photoelectron spectroscopy. According to the statistical results, the Zn/O ratio changes from Zn-rich for ZnO/Al2O3 films to O-rich for ZnO/GaN/Al2O3 films.
