Claim 1:
2. The method of claim 1, wherein a method for making the graphene nanoribbon composite structure comprising:
growing a graphene film on a growth substrate;
placing an adhesive layer on a surface of the graphene film away from the growth substrate;
removing the growth substrate, and cleaning with water or an organic solvent;
combining the graphene film, the adhesive layer, and the substrate; and drying, so that a plurality of wrinkles are formed near the plurality of protrusions, to obtain a first composite structure; wherein the first composite structure comprises the substrate, the graphene film, and the adhesive layer; and the graphene film is between the adhesive layer and the substrate;
removing the adhesive layer to obtain a second composite structure comprising the substrate and the graphene film, wherein the graphene film is located on the substrate; and
etching from a surface of the graphene film away from the substrate, to remove the graphene films except for the plurality of wrinkles.
