Spiral design graphene nanoribbon

摘要

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.

1. A method for fabricating a graphene nanoribbon, said method comprising the steps of:
preparing a mask for application on a substrate, the mask including a continuous line of masking material spiraling outward from a first end of the line to a second end of the line; depositing a graphene layer over a surface of the substrate; applying the mask to the substrate over the graphene layer to achieve a masked portion of the graphene layer; first removing an unmasked portion of the graphene layer from the surface of the substrate; and second removing the masking material from a remaining portion of the graphene layer to leave a continuous spiral line of graphene on the surface of the substrate corresponding with the mask.
