Electromagnetic properties of Graphene Nanoribbon (GNR) and Comparison with SWCNT and Copper

Abstract

The need for smaller and faster electronics is increasing day by day. To achieve that, one important factor is to have interconnects that can transport high frequency signal across IC elements. With that goal in mind we have tried to find a suitable material that can be used as interconnects for high frequency circuit. A theoretical investigation is carried out for predicting electromagnetic characteristics of Graphene nano-ribbon (GNR) terahertz regime. For this we have looked into the electrical properties of GNR such as resistance, capacitance and inductance. Moreover to get the proper picture, a conventional metal (copper) and another nano-material SWCNT is used in the simulation to compare the performance and decide the better material. From our work we have seen that in the lower GHZ frequency SWCNT offers better group velocity however in higher frequency copper is a better choice.
