Abstract :
In this paper we follow a semiclassical approach based on the Boltzmann Transport Equation (BTE) to simulate and compare with experiments the low-field mobility (μ) and the high-field drift velocity (vd) of graphene nano-ribbons (GNRs) and graphene bilayers (GbLs). It is found that remote phonons originating in the substrate have a large impact on the mobility, whereas their impact on the saturation velocity is smaller than predicted by recently proposed simplified model.
