Abstract
Conductive islands (quantum dots) of graphene and few-layer graphene in a fluorinated graphene matrix were produced by chemical functionalization of graphene in aqueous hydrofluoric acid. The structures formed were investigated by measuring the current-voltage characteristics and by means of an atomic-force microscope used to measure the surface topography and lateral forces. The presence of conductive islands in the fluorinated matrix was shown, and their sizes were determined.
