摘要

我们演示了在ag基阈值开关(TS)器件中控制混合灯丝(HF)的驱动参数。为了在统计上改善TS行为，我们设计了TS操作过程中的成核能势垒、HF形状和空间排斥力。最后，我们证明了TS具有极低的关断电流(0.1 pA)，极高的选择性(> 109)，稳定的阈值电压(< 3%波动)，高的耐久性(> 109)，稳定的陡峭的亚阈值斜率~ 1 mV/dec，以及Ag基器件的高器件产率。

Highly-stable (< 3% fluctuation) Ag-based Threshold Switch with Extreme-low OFF Current of 0.1 pA, Extreme-high Selectivity of 109 and High Endurance of 109 Cycles

We demonstrate driving parameters to control the hybrid-filament (HF) in Ag-based threshold switching (TS) devices. To achieve statistically improved TS behavior, we engineer the nucleation energy barrier, shape of HF and steric repulsion force during TS-operation. Finally, we demonstrate TS with extremely low OFF current (0.1 pA), extremely high selectivity (> 109) with stable threshold voltage (< 3% fluctuation), high endurance (> 109) with stable steep subthreshold slope ~ 1 mV/dec, and high device-yield in Ag based devices.
