Abstract

To assess their potential for interconnect applications, the interplay between electrical and thermal transport in carbon nanofibers (CNFs) under high-current stresses is examined. Electrical properties of CNFs bridging tungsten-deposited gold electrodes are measured. Average voltage is recorded as a function of current in each current stress cycle, and the resulting average resistance is shown to decrease with increasing stressing current. This finding reveals an important effect of Joule heating on the resistance of carbon nanostructures.
