Abstract
A method of preparing graphene nanoribbons from a few-layer graphene film includes the steps of growing or placing a few-layer graphene film on a substrate, applying nanoparticles to a surface of the few-layer graphene layer on the substrate and performing chemical vapor etching. The resulting few-layer graphene nanoribbon has a thickness of between about 0.3 nm and about 50.0 nm and a width of between about 1.0 nm and about 20.0 nm.
