Abstract:
Abstract: The geometry of graphene nanoribbons plays an important role in determining its electronic behaviour. In this paper we investigate the transport properties of a quasi one-dimensional graphene nanoribbons (GNRs) device with a parabolic band structure near the Dirac point. An analytical model of mobility is implemented by using the conductance approach and Drude model. The conductance of graphene nanoribbon device is calculated to obtain the mobility. The mobility is calculated and observed that increasing the nanoribbon temperature, affects the conductance and mobility. Also, highest mobility occurs at the Dirac point where the gate voltage is equal to the threshold voltage. Our results are in good agreement with recent experimental data.
