(a) Optical transmittance spectra of the SLG and MLG electrodes transferred onto a glass substrate following UV/ozone treatment. The inset provides a photo image of graphene film transferred onto a glass substrate with different numbers of graphene layers, from single (G1L) to multi (G2L, G3L, G4L, G5L and G6L) layers. (b) The optical transmittance for G4L increased by at least ~1% after UV/ozone treatment because of the resulting cleaner surface. (c) Raman spectra and (d) sheet resistance of the graphene films with increasing numbers of transferred graphene layers from G1L to G6L.
