    • Abstract


      The effect of tailoring the graphene sheets used as channel in a graphene nanoribbon field effect transistor (GNRFET) was investigated. The study was performed using self-consistent solution of Poisson's and Schrodinger's equation in combination with non-equilibrium Green's function (NEGF) formalism. Graphene sheet channel was tailored into different shapes and found that with the introduction of edge roughness along the border of GNR sheet the bandgap of GNRFET channel increases. Tailoring the channel decreases mobility and transmission probability to a great extent and thus the performance of I–V characteristics of GNRFET degrades.
