Özet

This paper presents electrical parameter extraction for metallic graphene nanoribbon (GNR) interconnects utilizing ab initio approach. Unlike the studies taking the kinetic inductance, quantum capacitance and Fermi velocity as constant values, voltage-dependencies of these parameters are obtained for GNR transmission line model. The variations of the kinetic energy and the current by the applied voltage are taken as bases for voltage-dependent kinetic inductance calculation. Quantum capacitance and the Fermi velocity are also computed from the kinetic inductance variation. It is concluded that voltage-dependencies of the kinetic inductance and the quantum capacitance have to be taken into account for accurate GNR modelling in nanoelectronic design.
