▎ 摘　　要

NOVELTY - The ribbon of graphene, is claimed. The ribbon of graphene has a width of less than 1 mm, where the width of the ribbon is one of the following dimensions: the length of 2 phenyl rings fused together; the length of 3 phenyl rings fused together; the length of 4 phenyl rings fused together; and the length of 5 phenyl rings fused together. A variation of thickness of the ribbon is less than 1 Angstrom . Edges of the ribbons are parallel to each other. The ribbon of graphene provided with surface and arm chair edges is in physical contact with surface of single crystal substrate. USE - The ribbon of graphene is useful in a FET structure and three or two terminal device structure (all claimed), and in an electronic device such as diode. ADVANTAGE - The ribbon of graphene improves the device characteristics of the FET. DETAILED DESCRIPTION - The ribbon of graphene, is claimed. The ribbon of graphene has a width of less than 1 mm, where the width of the ribbon is one of the following dimensions: the length of 2 phenyl rings fused together; the length of 3 phenyl rings fused together; the length of 4 phenyl rings fused together; and the length of 5 phenyl rings fused together. A variation of thickness of the ribbon is less than 1 Angstrom . Edges of the ribbons are parallel to each other. The ribbon of graphene provided with surface and arm chair edges is in physical contact with surface of single crystal substrate. The surface of the substrate is reconstructed to form rows with a unidirectional orientation. The substrate causes a widest surface of a precursor of the graphene ribbon to become in surface to surface contact with the substrate when the precursor is placed in proximity (e.g. van deer Waals bond distance) to the substrate. INDEPENDENT CLAIMS are included for: (1) a FET structure; (2) a method of making a ribbon of graphene; (3) a method of making a FET; (4) a three or two terminal device structure; and (5) planes of ribbons of graphene. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a process for producing graphene nanoribbon with armchair long edges.
