We fabricated multilayer graphene (MLG) on n-GaN substrate directly without extra catalyst by solid phase precipitation. The characterization made by Raman Spectroscopy and SEM revealed that the MLGs produced were crystalline and crystallinity was increased with annealing temperature. With further improvement of MLG quality, this might be a method for MLG fabrication on GaN for diode application.
