Carrier Mobility Study in Zinc doped Armchair Graphene Nanoribbon via Phonon Interactions

Abstract

Electron mobility which is one of the important electron transport parameters is calculated for zinc doped armchair graphene nanoribbon (aGNR) via electron acoustical phonon interactions on the basis of acoustical deformation potential (ADP) coupling mechanism. The lower doping concentration (x = 1%) is considered in this study. Moreover, the impact of magnetic field is studied on electron mobility. It has been observed that the acoustical deformation potential contributed electron mobility decreases as the strength of magnetic field increases. In addition to this we have also observe that the scattering rate of electrons traversing through the nanoribbon rises with increasing strength of magnetic field which is due to the fact that the electron effective mass increases with increasing strength of magnetic field.
