title: Chemical modification of epitaxial graphene: spontaneous grafting of aryl groups.
abstract: The addition of nitrophenyl groups to the surface of few-layer epitaxial graphene (EG) by the formation of covalent carbon-carbon bonds changed the electronic structure and transport properties of the EG from near-metallic to semiconducting.
