Using infrared spectroscopy, the authors investigate bottom gated ABA-stacked trilayer graphene subject to an additional environment-induced p-type doping. They find that the Slonczewski-Weiss-McClure tight-binding model and the Kubo formula reproduce the gate voltage-modulated reflectivity spectra...
