Novel spatially arranged mixed carbon nanotube bundle interconnects - Impact on delay and power

This research paper introduces novel structures of Mixed CNT Bundle (MCB) based non-conventional arrangements of single- and multi-walled carbon nanotubes. A hierarchical Equivalent Single Conductor (ESC) model is used to analyze the propagation delay and power dissipation of CNT bundles. The hierarchical model of MCB considers two types of CNT: one Single-Walled CNT (SWCNT) and other Multi-Walled CNT (MWCNT). The ESC model of MCB is a combination of ESC models of bundled SWCNT and bundled MWCNT. Initially, simple ESC models of bundled SWCNT and bundled MWCNT are derived, considering parasitic elements like resistance, capacitance and inductance. Later, these two equivalent models are combined to build up the nal ESC model of novel MCBs. It has been observed that the overall delay and power dissipation are reduced by 48.1% and 20.9%, respectively, for the novel MCB which has a horizontal arrangement of SWCNTs and MWCNTs in equal halves.
