The electrical properties of an advanced graphene FETstructure with local channel width modulation were theoretically investigated with the aim of increasing the local electric field along the channel and creating a bandgap by introducing a graphene nanoribbon (GNR) array. A semi-classical Monte Carlo particle method was used to simulate near ballistic electron transport combination with ab-initio calculation for successfully determining electronic states. Performance improvement was achieved in terms of the carriers' transit time, even though there was a tradeoff between the bandgap creation and electron mobility in graphene.
