Multi-Buffer Layers Effect on Characteristic of GaN Grown by MOCVD
|
Abstract:
GaN films were grown with different multi buffer layers by MOCVD.X ray diffraction and photoluminence were applied to study the characteristic of GaN films.Compared to GaN film with conventional single low temperature buffer layer,the FWHM of (0002) XRD and PL of GaN films with different multi buffer layers were narrowed.It indicated that these multi buffer layers techniques could improve crystal quality of GaN films.
