Abstract

Solution-processed graphene inks using ethyl cellulose polymer as a binder/stabilizer were blade-coated into large area films. Systematic charge transport characterization showed graphene patterns with high mobility ( 160 cm2 V-1 s-1), low energy gap, thermally activated charge transport and semiconducting character, which developed weak localization behavior at cryogenic temperatures
