▎ 摘 要
NOVELTY - Preparing graphene membrane comprises adopting physical method to release the carbon atom from a solid carbon source to form the graphene membrane on a catalyst layer. USE - The graphene membrane is useful for preparing high performance optoelectronic devices. ADVANTAGE - The method: is simple, since it utilizes solid carbon source. The thickness, structure and size of the graphene membrane is easy to control and the membrane has excellent photo-electric property.
