Modeling of Joule Heating Induced Effects in Multiwall Carbon Nanotube Interconnects

Strontium-deficient SrxCoO2–CoO2 nanotubes as a high ampacity and high conductivity material

“…Like CNTs, the maximum current density decreases with increasing diameter and channel length. 29 The best value is observed for an NT with a diameter of 13.5 nm and a channel length of 176 nm. The reason behind this can be explained by the Joule heating associated with current conduction.…”

“…6(a) shows a comparison plot of ampacity vs conductivity for metals and nanocarbons and nanocarbon composites. [12][13][14][15][16][17][18][19][20][21][22][23][28][29][30][31][32][33][34][35][53][54][55][56][57][59][60][61][62] SCO-NTs are found to be one of the best materials next to the best reported CNT-Cu composite 55 and c-Al NW 56 showing a higher ampacity at slightly reduced conductivity. Considering the fact that achieving high ampacity and conductivity in the same material is challenging, SCO-NTs hold a potential chance to replace the existing interconnects (metals) in the future.…”

“…12–23 and van der Waals materials 24–27 and even comparable to that of multi-wall carbon nanotubes (MWCNTs) (1.23 × 10 8 A cm −2 ). 28–30 Compared to the state-of-the-art materials, e.g. , graphene, 31,32 MWCNTs, 33 and single-wall (SW)CNTs, 33–35 SCO-NTs show higher conductivity ( σ ) on the order of 1.28 × 10 4 S cm −1 , which is one order of magnitude higher than that of SWNTs and graphene.…”

“…[12][13][14][15][16][17][18][19][20][21][22][23] and van der Waals materials [24][25][26][27] and even comparable to that of multi-wall carbon nanotubes (MWCNTs) (1.23 Â 10 8 A cm À2 ). [28][29][30] Compared to the state-of-the-art materials, e.g., graphene, 31,32 MWCNTs, 33 and single-wall (SW)CNTs, [33][34][35] SCO-NTs show higher conductivity (s) on the order of 1.28 Â 10 4 S cm À1 , which is one order of magnitude higher than that of SWNTs and graphene. Besides, SCO-NTs exhibited a high breakdown power per unit channel length (P/L) B 38.3 W cm À1 , which is the highest among all of the regularly used interconnect materials and close to the highest reported value for boron nitride coated-SWNTs (B45 W cm À1 ).…”

Mini-Review: Modeling and Performance Analysis of Nanocarbon Interconnects

“…Further, some studies have been conducted to analyze the crosstalk, variability, Joule heating, and electrostatic discharge (ESD) reliability of CNT interconnects [64,[74][75][76][77][78][79][80][81][82][83].…”
