Graphene nanoribbons (GNRs) have recently attracted intensive interest as promising building blocks for nanoelectronic and spintronic devices. Theoretical studies on the electron transport in GNRs with perfect edges have been reported. However, any GNRs initially made are likely to have irregular edges. The important role of edge roughness on both electronic structures and transport have been examined experimentally, but a consistent theoretical investigation is still absent. The edge effects on the device performance is essential to get a more accurate picture for Joule heating and wind force in GNRs. In this research, edge scattering will be studied at first and then combined with other phonon scattering mechanisms by Monte Carlo simulations.
