Abstract

The upwind self-electromigration of liquid metal is demonstrated by in situ transmission electron microscopy technique. Our direct observation shows that a dc current through a liquid Gallium (Ga) nanobridge can maintain a steady nanofluidic flow along the liquid bridge itself. Among all the liquid bridges, the minimum width we achieved in the experiments reaches 3.5 nm. It has been revealed that the onset migration current density is directly related to the width of the bridge. These experimental observations provide insights into the physical picture of electromigration as well as opportunities for potential applications.
