Abstract

We study the transport of carriers in intrinsic graphene by means of an ensemble Monte Carlo technique. Scattering by acoustic and optical phonons dominates the transport. We find that velocity 'saturation' sets in at relatively low values of the electric field, but that the value is dependent upon the carrier density. Velocity overshoot is also observed to occur in these simulations.
