"NANOTECH: Team exploits electromigration to build nanosystems"
Chip designers usually take pains to avoid electromigration, an effect that plagues metal layers, especially aluminum. But now, researchers at Lawrence Berkeley National Laboratory have harnessed electromigration down carbon nanotube "pipelines" to deliver a constant stream of indium atoms to nanoelectromechanical systems (NEMS).
