Abstract

In this letter, we propose a gallium oxide/oxygen doped silicon nitride-based resistive switching device for removing sneak-path currents in high-density crossbar array structures. The device exhibited diodelike characteristics owing to a simple Schottky contact and ultralow power operating behavior (∼ 0.5 V, 1 μA) without any forming process. Both ON/OFF and rectification ratios exceeded 10³, and the fastest ac-pulse program (erase) time was 50 (80) ns. The ac-pulse program and erase tests showed 10⁵ cycle endurance without degradation, and dc test showed over 10² cycle endurance. Furthermore, data retention time was > 10⁵ s at room temperature.
