▎ 摘　　要

NOVELTY - The graphene-emitting diode structure has a triangular graphene nanostructure whose width gradient is projected along the extended side surface of diode main portion. A narrow two rectangle portions are connected with graphene nanostructures. The graphene nanostructure is composed of negative type and positive type doping graphene nanostructure. USE - Graphene-emitting diode structure used for diode logic gate (claimed). ADVANTAGE - The design pattern of the diode structure can be realized so as to form complete logic circuit. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for diode logic gate. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the graphene-emitting diode structure. Lengths of graphene nanostructure (L1-L3) Widths of graphene nanostructure (W1-W6)
