Comparative analysis of TL models for multilayer graphene nanoribbon and multiwall carbon nanotube interconnects

The multiconductor transmission line model of a multilayer graphene nanoribbon (MLGNR) interconnect is proposed for the analysis of current distribution and signal propagation at radio frequency (RF) up to 100 GHz. The equivalent single conductor model is also developed in order to analyse the common mode propagation. The comparison of the RF performances of a MLGNR interconnect and a multi-wall carbon nanotube (MWCNT) interconnect is also performed. The obtained results show that the MLGNR interconnect has a higher current carrying capability than an MWCNT nanoline having the same dimension and configuration above the ground.
