Abstract

The appearance and evolution of surface dislocations on the surface of flame-annealed gold films due to current stressing (electromigration) are studied using scanning tunneling microscopy. Many line dislocations are present on the surface of such films, probably formed during the annealing process. Yet, at room temperature, with no current stressing, the formation of new surface dislocations is rare. When a current is applied through the film, new line dislocations often emerge. The new dislocations run predominantly in directions close to that of the current, and usually appear in correlation with the onset of the current.
