Spiral design graphene nanoribbon

Abstract

Graphene nanoribbons and methods for fabricating graphene nanoribbons, particularly those with long lengths, are provided. In one embodiment, a method (400) for fabricating a graphene nanoribbon (100) includes preparing (410) a mask for application on a substrate (102). The mask may include a continuous line of masking material spiraling outward from a first end (104) of the line to a second end (106). The method (400) also includes depositing (420) a graphene layer (108) over a top surface (102A) of the substrate (102), applying (430) the mask to the substrate (102) over the graphene layer (108), removing (440) an unmasked portion of the graphene layer (108), and removing (450) the masking material from a remaining portion of the graphene layer (108) to leave a continuous line of graphene on the surface (102A) of the substrate (100) corresponding with the mask.
