Claim Text:
1. A method for forming a vertical graphene material structure on a substrate surface, comprising the steps of: forming a substrate; depositing a carbon or a carbon-containing material (CCCM) layer on the surface of the substrate; depositing a patterned metal material layer of a patterned metal material on the CCCM layer to form a CCCM/patterned metal material layer structure, the patterned metal material layer having a bottom surface in contact with the CCCM and further having top and side surfaces not in contact with the CCCM; applying a heating/cooling cycle to the CCCM/patterned metal material layer structure to diffuse carbon from the CCCM into the patterned metal material to form a carbon-containing patterned metal material layer, the CCCM being wholly or partially consumed during the heating/cooling cycle; cooling the carbon-containing patterned metal material layer to precipitate carbon out of the carbon-containing metal material layer to form a first graphene material (GM) on the bottom surface of the carbon-containing patterned metal material layer adjacent to the substrate and to form a second graphene material (GM removing the carbon-containing metal material layer without removing the GM; and removing any remaining CCCM layer not consumed during the heating/cooling cycle; wherein the GM remains on the surface of the substrate; and removing the GM wherein the GM
