Graphene is a single monolayer thick carbon sheet with remarkably high electron mobility. Its unique structural and electronic properties make it an interesting material for nanoscale electronic and sensing devices. The addition of functionalities increases its reactivity toward certain materials and thus broadens its applications. One significant impediment to realizing the potential of graphene is the development of an industrially viable approach to producing precisely engineered functionalities over large areas. In this respect, plasmas are an ideal candidate but problems associated with the large fluxes of high-energy ions are a significant concern. Electron beam generated plasmas, characterized by low incident ion energies (< 5 eV), have been used to functionalize graphene without any damage [1]. We discuss the use of this system to controllably introducing oxygen, hydrogen, fluorine, nitrogen or ammine containing groups at different concentrations. The reversibility of the functionalization via low-temperature annealing will also be discussed. This work was supported by the Office of Naval Research. M.B. appreciates the support of the National Research Council.
