Fluorographene (FG) photodetectors. (a) device schematic of a FG/graphene PD; (b) domain structure of partially-fluorinated graphene and corresponding lifetimes of photoexcited charges (left). Trapping and relaxation schematic in FG responsible for the observed photo-response; (c) responsivity as a function of incident power density for multiple wavelengths and (d) comparison of noise equivalent power (NEP) as a function of incident wavelength for a graphene/graphene and a FG/graphene device.
