| Outline of Final Research Achievements |
We carried out direct growth of graphene layers on sapphire substrates by liquid phase epitaxial growth (LPE) using Ga as melts. In this growth, we used SiC powders and amorphous carbon layers as source materials, and the grown graphene layers were characterized by Raman and X-ray photoelectron spectroscopy (XPS). Even when SiC powders were used, graphene with several layers were grown. When amorphous carbon layers (1.3 nm in thickness) were used, good quality graphene layers were obtained. The thickness of the graphene layers were estimated to be 1-2 nm.
