Growth of Good GaN Single Crystal Film on ZnO/Al 2O 3 Substrate |
| |
Abstract: | It is reported that GaN was grown on ZnO/Al 2O 3 substrate by LP MOCVD, and its characteristics were studied. The experimental results show that the GaN buffer is necessary for improving the quality of GaN epitaxial layer. The main peak of GaN epitaxial layer photoluminescence moves to blue spectrum, which has been confirmed that the diffusion of Zn in ZnO layer into GaN is responsible. |
