  • Patent number: 8921824
    Abstract: A three-dimensional graphene structure, and methods of manufacturing and transferring the same including forming at least one layer of graphene having a periodically repeated three-dimensional shape. The three-dimensional graphene structure is formed by forming a pattern having a three-dimensional shape on a surface of a substrate, and forming the three-dimensional graphene structure having the three-dimensional shape of the pattern by growing graphene on the substrate on which the pattern is formed. The three-dimensional graphene structure is transferred by injecting a gas between the three-dimensional graphene structure and the substrate, separating the three-dimensional graphene structure from the substrate by bonding the three-dimensional graphene structure to an adhesive support, combining the three-dimensional graphene structure with an insulating substrate, and removing the adhesive support.
