Current capacity and thermal transport in carbon nanofiber interconnects

Carbon nanofibers (CNF) are studied in a horizontal configuration as a model for on-chip interconnects. The electrical performance is determined by both CNF resistivity and contact resistance with electrodes. Reliability and current capacity are determined by Joule heating in the system and the thermal accompanying transport. We show that current capacity can be modeled by accounting for the nature of the contacts with the substrate and with the electrodes.
