Metal Deposition by Inducing a Microgalvanic Cell with the Scanning Electrochemical Microscope (SECM)

A new mechanism of metal deposition on conducting surfaces is presented. But in contrast to former procedures where metal ions were deposited by electrolysis on a conducting cathodically polarised surface, now the deposition occurs without any additional electrochemical energy even if the substrate metal is more noble than the deposited metal...
