Title
Comparative Radio-Frequency And Crosstalk Analysis Of Carbon-Based Nano-Interconnects
Abstract
A comparative radio-frequency (RF) and crosstalk analysis is performed on carbon nano-interconnects based on an efficient pi-type equivalent single-conductor model of bundled multiwall carbon nanotubes (MWCNTs) and stacked multilayer graphene nanoribbons (MLGNRs). Simulation results are extracted using HSPICE for global-level nano-interconnects at the 14-nm node. RF performance is evaluated in terms of skin depth and a 3-dB bandwidth, while crosstalk performance is analysed in terms of crosstalk-induced delay and average power consumption. The skin-depth results indicate significant improvements in skin-depth degradation at higher frequencies for AsF5-doped zig-zag MLGNRs compared with that of Cu, nanotubes and MWCNTs. The transfer gain results explicitly demonstrate that AsF5-doped MLGNRs exhibit excellent RF behaviour, showing 10- and 20-fold improvements over MWCNTs and copper (Cu), respectively. Further, the 3-dB bandwidth calculations for AsF5-doped MLGNRs suggest 18.6- and 9.7-fold enhancement compared with Cu and MWCNTs at 1000 mu m. Significant reductions are obtained in crosstalk-induced out-of-phase delays for AsF5-doped MLGNRs-their delay values were 84.7% and 60.24% less than those for Cu and MWCNTs. Further, AsF5-doped MLGNRs present the most optimal energy-delay product results, with values representing 98.6% and 99.6% improvements over their Cu and MWCNT counterparts at a global length of 1000 mu m.
