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.
