▎ 摘　　要

NOVELTY - A three-dimensional graphene structure (A1) (4) comprises at least one layer of graphene having a periodically repeated three-dimensional shape. USE - As three-dimensional graphene structure useful for making electronic device (claimed) e.g. display device, transparent electrode for solar cell, transistor, sensor, and channel material of memory. ADVANTAGE - The 3-dimensional graphene structure exhibits improved integrity and performance. The 3-dimensional graphene structure improves the integrity and performance of various electronic devices; and minimizes the defects that occur during a transferring process. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacturing (M1) a three-dimensional graphene structure involving forming a pattern having a three-dimensional shape on at least one surface of a substrate (2), 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; (2) transferring (M2) a three-dimensional graphene structure involving reducing a connection strength between the three-dimensional graphene structure and the substrate by injecting a gas between it, separating the three-dimensional graphene structure from the substrate by bonding the three-dimensional graphene structure to an adhesive support (6), combining the three-dimensional graphene structure with an insulating substrate, and removing the adhesive support; (3) an electronic device comprising the three-dimensional graphene structure; and (4) a three-dimensional graphene structure (A2) comprising a sheet of graphene having a first set of carbon atoms extending along a first plane and a second set of carbons extending along a second plane substantially parallel to the first plane, where the first set of carbon atoms are bonded to the second set of carbon atoms. DESCRIPTION OF DRAWING(S) - The figure shows a view of a substrate on which an adhesive tape is bonded to graphene. Substrate (2) Three-dimensional graphene structure (4) Adhesive support (6)
