▎ 摘　　要

NOVELTY - Growing a one or two monolayer film of graphene on a substrate, comprises: depositing a first layer of graphene on the substrate by physical vapor deposition to form a carbon layer on the substrate, and annealing the carbon layer to form an ordered graphene layer one or two monolayers thick on the substrate, where the further deposition and annealing of carbon on the graphene does not result in the formation of additional graphene layers. USE - The method is useful for growing a one or two monolayer film of graphene on a substrate. ADVANTAGE - The method can be carried out in a simple and cost-effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a composition of matter comprising a substrate on which is formed a film of one or two monolayer graphene exhibiting a band gap of at least 0.5 eV.
