摘　　要：In this paper,the single-walled carbon nanotube(SWCNT)with graphene nanoribbon(GNR)inside,namely GNR@SWCNT,is proposed as alternative conductor material for the interconnect applications.The equivalent circuit model is established,and the circuit parameters extracted analytically.By virtue of the equivalent circuit model,the signal transmission performance of GNR@SWCNT bundle interconnect is evaluated and compared with its Cu and SWCNT counterparts.The optimal repeater insertions in global-and intermediate-level GNR@SWCNT bundle interconnect are studied.Moreover,it is demonstrated that the GNR@SWCNT interconnects could provide superior performance,indicating that GNR@SWCNT structure would be beneficial for development of future carbon-based integrated circuits and systems.
