Modelling of self-heating effects in multi-wall carbon nanotube interconnects

Self-heating effects of individual multi-wall carbon nanotubes (MWCNTs) are investigated for nanometre-scale interconnect applications. Based on the previous experimental data, an empirical thermal conductivity model for individual MWCNTs is proposed. The heat transport equation is then derived and solved to attain the temperature distributions along the tubes. Numerical results illustrate that only at high bias and for short tube length does the self-heating need to be considered.
