| مستخلص: |
We report the surface morphology of multilayer graphene synthesized directly on a SiO2/Si substrate through graphitization of amorphous carbon with Ni catalyst. We demonstrate that the disorder-induced Raman D peak is effectively suppressed when the Ni catalyst layer is covered with Au layer. Scanning electron microscope observation reveals that the Au layer prevents granulation of Ni after the annealing process, leading to the formation of continuous graphene with less holes.
