New comprehensive stability and sensitivity analysis on Graphene nanoribbon interconnects parameters

Abstract

Based on the transmission line modeling for multilayer graphene nanoribbon (MGNR) interconnects, system stability was studied on intrinsic parameters. In addition to width, length and height variation, dielectric constant, permeability and Fermi velocity path change in multilayer graphene nanoribbon (MGNR) interconnects are analyzed. In this paper, the obtained results show with increasing dielectric constant and decreasing permeability, Fermi velocity system becomes more stable. Nyquist diagram and step response method results confirm these and are matched with physical parameter variation like resistance, capacitance and inductance in the following sensitivity analysis results where it shows with increasing width and length, sensitivity will decrease and increase respectively. Impulse response diagram results show with increasing 50% width, sensitivity will be zero but with increasing 50% length, amplitude will decrease and the time of setting will increase. On the other hand, from the step response of the transfer function, both width and length increase cause more stability for a system but the width parameter will be a better choice for manipulating the dimension of MGNR to reach a stable system.
