Temperature-dependent electromigration measurements have been performed and a model incorporating Joule heating is used to describe those. An activation energy for diffusion between 100 and 180meV is found. Furthermore, in-situ electromigration experiments have been performed in a scanning electron microscope. This allowed us to link events in the conductance traces of bismuth constrictions during electromigration to visual features. Specifically, remerging of the bismuth electrodes was found to cause increases in conduction.Show less
