Abstract :
A fully analytical model for the quantum capacitance of AGNR-FETs is proposed in order to explore several finite-size and edge effects. It is demonstrated that, the quantum capacitance of sub-10 nm AGNRs versus channel potential, has a non-monotonic behavior with peak values and corresponding channel potentials which are strongly dependent on the ribbon´s width and edge effects.
