Imaging accumulated charges at solid-electrolyte interfaces

Researchers have developed a three-dimensional open-loop electric potential microscopy technique to visualize the charge accumulation behavior at the interface between a solid electrode and liquid electrolyte. The technique was used for providing information about the charge distribution at the interface between a copper wire electrode and salt-based electrolyte. This technique increases our ability to probe nanoscale interfacial phenomena, making it useful for research in electronics, electrochemistry, and biology.
