Abstract
RECENTLY a technique has been developed1 for impressing an electrical potential difference across a growing oxide film; in this technique a metallic film, porous to oxygen is used as an electrode. The success of this technique, in contrast to earlier techniques2,3, is attributed3 to the fact that the potential drop occurs primarily across the oxide film instead of across some other portion of the circuit (for example, the vacuum portion of a capacitor). Some difficulties may arise in the interpretation of experimental results using such a technique, however, due to the introduction of a second metal–oxide junction4 not intrinsically a part of the oxidation system.
