In this work, we have grown a-plane ZnO films on a-plane GaN/r-sapphire templates by pulsed laser deposition. The aplane
GaN of the templates is aimed to mitigate the large lattice mismatch between ZnO and sapphire, and was grown by
metal organic chemical vapor deposition. The grown a-plane ZnO films have been analyzed by various techniques such
as high resolution X-ray diffraction, photoluminescence. It shows that high quality a-plane ZnO films have been
achieved by our growth method.
