Fabrication of fluorinated graphene layers and transistor devices. Crystal structure of pristine graphene (a) and fluorinated graphene (b). The grey balls in (b) represent the carbon atoms, whereas the green balls are the fluorine atoms. Optical image of pristine graphene (c) and of fluorinated graphene (d). (e) False colour SEM image of a fluorinated graphene device. (f) Schematic view of the transistor structure fabricated on fluorinated graphene.
