Raman Scattering of GaN Epilayer |
| |
| Abstract: | Abstract We have measured the Raman scattering of GaN epilayer grown by MOVPE on AgAl 2O 4 substrate.The results show that the epilayers have a good crystal quality. All symmetry allowed optical phononsin GaN were observed in the back scattering and rightangle scattering configurations. The quasi LO and TO modes have also been observed in the X(Y,Y)ZandX(Z,X)Z configurations. The Raman spectra of GaN epilayer grown by MBE on (0001) and (0 11- 2) sapphire have also been measured and discussed. |
