Abstract
MgZnO/ZnO heterostructure was fabricated on sapphire substrate by plasma assistant molecular beam epitaxy. The micro-photoluminescence spectra of sample are reported, which shows that different emission peaks would appear when the laser beam focuses different deepness in the film. A carrier tunneling process from the MgZnO capping layer to ZnO layer was observed by the measured temperature dependence of photoluminescence spectra. This induces the emission intensity of the ZnO grew monotonically from 81 to 103Â K.
