発明の名称 (英語) METHOD FOR PRODUCING GRAPHENE, GRAPHENE PRODUCED ON SUBSTRATE, AND GRAPHENE ON SUBSTRATE
発明の概要(英語)

A production method for producing graphene on a substrate is provided, etc. The method has a formation step in which a solid solution containing carbon dissolved in a metal is formed by being heated to a solid solution temperature at which the solid solution can be formed, and a solid solution layer (505) composed of the solid solution is formed on a substrate (103). In a removal step, the metal is removed from the solid solution layer (505) while the solid solution is kept heated at the solid solution temperature, thereby causing graphene (102) to grow on the substrate (103). Various alloys can be used in addition to metals composed of a single element as a solvent for forming carbon into a solid solution. Removing the metal from the solid solution layer (505) by feeding an etching gas brings the graphene (102) into contact with the substrate (103).
