NOVELTY - Growing graphene nanoribbon involves depositing aromatic molecular seeds from the gas phase onto a surface of a growth substrate, and growing graphene nanoribbon from the aromatic molecular seeds via chemical vapor deposition. USE - Method for growing graphene nanoribbon. ADVANTAGE - The method can promote anisotropic directional growth of graphene nanoribbons by performing chemical vapor deposition (CVD) growth of graphene, and has armchair edge and high aspect ratios can be grown with a very low size polydispersity.
