Modeling Issues and Performance Analysis of High-Speed Interconnects Based on a Bundle of SWCNT

The effects of the uncertainties associated with the transverse pattern of carbon nanotubes (CNTs) of the conducting type in a semiglobal interconnect based on a densely packed CNT bundle are investigated. The effectiveness of the insertion of a variable number of repeaters along the interconnect and the influence of the contact resistances between CNTs and external circuitry are also studied. The numerical computations are performed by using a multiconductor transmission line model in which the per-unit length parameters are accurately derived from a macroscopic fluidlike description of the conduction phenomena in CNTs.
