  • Abstract
    We propose the feasibility of bidirectional selection device characteristics in ultrathin (<;3nm) TiO2 layer. We utilized the localized conducting path as virtual electrode to investigate device property at extremely scaled area. By using electrical method such as “forming” and “reset” processes in oxide, virtual electrode/sub-3nm-thick TiO2/virtual electrode structure was achieved. The measured current-voltage characteristics of fabricated device exhibited uniform bidirectional selection behavior with a high selectivity (~105) and showed the feasibility of high current density (>;106A/cm2).
