论文摘要
我们强调温度在解释无定形相变材料的IV卵子阈值开关曲线中的作用。通过考虑温度对无定形材料电导率的影响，可以补充普通 - 弗兰克尔传导模型，我们发现与各种可用数据一致。这导致了对阈值切换中快回的简单解释。我们还认为，无定形状态中的低频电流噪声源于移动电荷载体的火车，这是由于无定形材料中不同的局部结构而导致的。
We emphasize the role of temperature in explaining the IV ovonic threshold switching curve of amorphous phase change materials. The Poole-Frankel conduction model is supplemented by considering effects of temperature on the conductivity in amorphous materials and we find agreement with a wide variety of available data. This leads to a simple explanation of the snapback in threshold switching. We also argue that low frequency current noise in the amorphous state originates from trains of moving charge carriers derailing and restarting due to the different local structures within the amorphous material.
