Atomistic study of field emission current from graphene nano-ribbon and effect of strain on field emission current

In this report, we present a modification in non-equilibrium Green's function method to investigate structural effects of the emitter on field emission current. Effect of applied uniaxial strain can also be studied using our modified formalism. Moreover a practical method to consider the effect of device parameters such as channel length, anode-cathode separation and gate potential can be provided by the proposed formalism.
