摘要
利用LP-MOCVD在ZnO/Al2O3衬底上生长了GaN。实验发现低温生长GaN过渡层有利于晶体质量的提高;样品PL谱主峰红移到蓝光区。
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.
