Abstract: Oxygen-rich polycrystalline NiOx films were prepared by means of magnetron sputtering. Thickness-dependent bipolar resistive switching behaviors revealed that the 20 nm-thick NiOx film presented a clockwise current-voltage loop, while the 60 nm-thick NiOx film achieved an anti-clockwise current-voltage loop. Redox reactions between penetrated Ag ions and drifted oxygen ions in the whole 20 nm-thick NiOx films resulted in the clockwise current-voltage loops. Filamentary conducting paths composed by oxygen vacancies were responsible for the anti-clockwise resistive switching loops of the 60 nm-thick NiOx film.
