Graphical AbstractA GNR-FET with different lengths of the channel are studied by self-consistently solving the nonequilibrium Green’s function transport equation in an atomistic basis set with a 3-D Poisson equation. Fig., IS–D versus Vgate for different values of the channel length and doping with Vdrain=0.3V. Highlights► The ballistic performance of armchair graphene nanoribbon (GNR)-FET with doped source and drain at different lengths of the channel are studied by self-consistently solving the nonequilibrium Green’s function (NEGF) transport equation in an atomistic basis set with a 3-D Poisson equation. ► The source-drain current for simulated GNR-FET shows length-independent over-the-barrier ballistic transport at high gate-voltages, while at low gate voltages, direct source to drain under-the-barrier tunnelling results in decreased amount of the current with increasing the length of the channel. ► At low doping the over-the-barrier ballistic current is dominant while at high doping because of the large shift of the conduction band at the source and drain contacts, under-the-barrier tunnelling current is dominant. ► The cut-off frequency decreases by increasing the channel length as is the case for traditional MOSFETs. The increased frequency with decreasing the doping is another result that arises from the short channel effects on the potential profile of ballistic nano graphene FETs.
