Modification of the Properties of Vanadium Oxide Thin Films by Plasma-Immersion Ion Implantation

Figure 9

Colored spot area as a function of time of voltage application: the negative electrode is located on nonhydrogenated region and the positive one on hydrogenated region (see insert); both electrodes are on as-prepared (nonhydrogenated) film; both electrodes are on hydrogenated film; the negative electrode is located on hydrogenated region, and the positive one on initial film.
