Abstract

A method of forming a multi-layer graphene includes forming a stack of a graphitizing metal catalyst layer and graphene by repeatedly performing a cycle of first forming the graphitizing metal catalyst layer on a substrate, and then forming the graphene on the graphitizing metal catalyst layer, and removing the graphitizing metal catalyst layer.
