Mechanism of Anodic Germanium Oxide Film Formation

Abstract

Voltage transient studies were made on the electrode in a system of acetic anhydride containing small amounts of acetic acid, water, and lithium nitrate. These studies indicate that water diffuses into and through the film, that it reacts electrochemically at or near the interface, and that the hydrogen ion so produced moves back through the film as the current‐carrying species. Increasing the concentration of water in the film increases the conductivity by increasing the jump distance of the hydrogen ion.
