Abstract: Graphene nanoribbon arrays, methods of growing graphene nanoribbon arrays, and electronic and photonic devices incorporating the graphene nanoribbon arrays are provided. The graphene nanoribbons in the arrays are formed using a seed-mediated, bottom-up, chemical vapor deposition (CVD) technique in which the (001) facet of a semiconductor substrate and the orientation of the seed particles on the substrate are used to orient the graphene nanoribbon crystals preferentially along a single [110] direction of the substrate.

Abstract: Methods for the bottom-up growth of graphene nanoribbons are provided. The methods utilize small aromatic molecular seeds to initiate the anisotropic chemical vapor deposition (CVD) growth of graphene nanoribbons having low size polydispersities on the surface of a growth substrate. The aromatic molecular seeds include polycyclic aromatic hydrocarbons (PAHs), functionalized derivatives of PAHs, heterocyclic aromatic molecules, and metal complexes of heterocyclic aromatic molecules.
