Abstract

Electronic transport at the m length scale is theoretically investigated for N-doped and vacancy damagedgraphene nanoribbons. In these systems, localization due to scattering is strongly energy dependent, and thisfact leads to the appearance of conductance quasigaps in the spectral region of the resonance states. Conductancefluctuations are very large in the quasigap regions and increase linearly with the system size. The singleparameters scaling hypothesis is not verified for energies in a zone including the charge neutrality point whileit is valid for energies away from this zone
