We investigated the effect of layer-by-layer AuCl3 doping on the electrical and optical properties of stacked graphene films. Graphene grown by the chemical-vapor deposition method on a Cu-foil was chemically doped by AuCl3 solution with a concentration of 20 mM. Eight different configurations were prepared and analyzed by using four-point probe measurements, optical transmittance measurements, scanning electron microscopy, and micro-Raman spectroscopy to compare the optical and electrical characteristics of the different graphene samples. In our study, the top-layer doping method was very effective because better performances considering both sheet resistance and optical transmittance were observed from the configurations with the top-layer doped.
