Undoped GaN epilayers with different surface morphologies were grown by MOVPE
and surfaces of part of epilayers were polished. Luminescence distribution of deep levels
scattering light of defects
and Raman shift were measured by cathodoluminescence
light scattering
and Raman scattering
respectively. The results show that the defects in GaN epilayers influence not only on the luminescence and light scattering properties but also on the Raman shifts.
