Abstract

Surface acoustic wave delay lines with an operational frequency of 2.5 GHz have been designed to measure the acousto-electric transport of carriers in graphene transferred onto YX128°-LiNbO₃ piezoelectric substrate. The monolayer of graphene on LiNbO₃ presented sheet resistance in the range of 733-1230 Ω/□ and ohmic contact resistance with gold of 1880 to 5200 Ωμm. The measurements with different interaction lengths on graphene bars have allowed the extraction of carrier absorption and mobility parameters from acousto-electric current.
