From: Radical-assisted chemical doping for chemically derived graphene
Sheet resistance of different films as a function of optical transmittance at 550 nm. Pristine RGO films (black squares), doped RGO films by surface adsorption (blue triangles), and RGO + TCNQ complex films (red circles). The sheet resistance of the RGO + TCNQ complex films decreased drastically by two orders of magnitude, without degradation of optical transparency, which was a more drastic change than the case of doping by surface adsorption.
