We study the high‐field transport behavior of a graphene nanoribbon in the degenerate and nondegenerate regimes by incorporating a previous low field mobility calculation modified for a high electric field in both regimes. The drift velocity model presented predicts that the transport behaviour is different in each regime when subject to an electric field. Our theoretical results are comparable with experimental data. The Fermi velocity (for the degenerate regime) and thermal velocity (for the nondegenerate regime) coupled with optical phonon emission have a large influence on the drift velocity leading to a velocity saturation preceded by a monotonic increase with increasing electric field.
