NOVELTY - Growing of graphene on sapphire substrate involves decomposing carbon-based halide on sapphire substrate and using substrate for catalyzing growth. USE - Growing of graphene on sapphire substrate used for manufacturing device. ADVANTAGE - The method enables growth of graphene with large area, without using a metal catalyst and without requiring graphite transfer process. The graphene is used directly in the manufacture of various devices and provides devices with improved reliability, electrical characteristics and reduced complexity during fabrication.
