摘要
Thick film growth of nonpolar a-plane GaN was carried out on r-plane sapphire by direct synthesis method for a substrate of homoepitaxy of a-plane GaN. A 30 mu m thick a-plane GaN film was obtained at growth temperature at 1050 degrees C with a low-temperature buffer layer deposited at 700 degrees C. The surface was smooth but has some pits. Without a buffer layer, 20 mu m thick a-plane GaN with much fewer pits was obtained. The best FWHM of XRD peak in omega-mode obtained was less than 700 arcsec. This film can be used as a substrate for a-plane III-nitrides growth.
