Abstract

In situ X-ray Photoelectron Spectroscopy (XPS) was used to examine the interfaces formed by reactive sputter deposition of vanadia onto several lithium based solid glass electrolytes. It has been found that lithium migration to the vanadia/vacuum interface can occur during deposition and that the presence of lithium can influence the oxygen uptake during the reactive sputtering process. The lithium migration is driven by an electric field present due to the plasma; it is shown that the migration can be influenced by the deposition conditions.
