(color online) (a) Raman spectra of graphene, CNT network, G/CNT, and G-CNT films. (b) Optical transmittance and sheet resistance of typical graphene, CNT network, G/CNT, and G-CNT films on glass substrates. Due to the same nanostructures of the G/CNT and CNT/G hybrid films, their Raman spectra, optical transmittances, and sheet resistances are nearly the same.
