And Migration

The damage mechanisms of carbon nanotubes are considered to be the oxidation by Joule heating and migration of carbon atoms by high-density electron flows. In this study, a high current density testing system was designed and applied to multiwalled carbon nanotubes (MWCNTs) collected at the gap between thin-film electrodes. Local evaporation of carbon atoms occurred on the cathode side of the MWCNTs under relatively low current density conditions, and the center area of the MWCNTs under high current density conditions. The damaged morphology could be explained by considering both Joule heating and electromigration behavior of MWCNTs.
