METHOD FOR PRODUCING GRAPHENE, AND GRAPHENE PRODUCED BY THE METHOD

摘要

A method for producing grapheme is disclosed in which graphene is formed by supplying carbon to a heated transition metal surface, in order to form a high-quality uniform graphene film having no domain boundaries. The method includes forming a buffer thin film that is epitaxially grown on a Ni(111) substrate, and forming graphene on the buffer thin film. The buffer thin film is made of material selected from the group consisting of Fe, Co, Ni, Cu, Mo, Ru, Rh, Pd, W, Re, Ir and Pt, or from alloys thereof. The buffer thin film has a surface of three-fold symmetry or six-fold symmetry.
