Abstract
We present a novel selector made of doped-chalcogenide material. This selector not only achieves low holding voltage (0.2 V) and large on/off ratio (>107), but also exhibits the high on-current density (>1.6 MA/cm2) and large hysteresis window (1.2 V). Besides, excellent selector performances with ultra-low off-state leakage current (10 pA), high switching speed (<;10 ns), high endurance (>109), good thermal stability (up to 180°C) have been demonstrated. Furthermore, the device exhibits good scalability which is suitable for 3D array integrations.
