双端对称电压敏感开关器件Ovonic Threshold Switch （ots）是一种新型的电路元件，电路设计者必须对其进行特性分析，才能将其应用于实际。本文的目的就是完成这一任务。神学在静态和动态参数方面都具有特征。研究了电极的阻塞状态和导电状态。讨论了从阻塞状态到导电状态以及从导电状态到阻塞状态的开关实验。还包括对能量和电荷开关要求的研究，以及击穿前偏置电压和极性反转对导通机制的影响。静态和动态参数是根据温度、器件几何形状和其他参数来表征的。结果表明，在预击穿期间极性反转不影响延迟时间，而预偏置可以独立于极性降低延迟时间。
The Ovonic Threshold Switch (ots), a two-terminal symmetrical voltage sensitive switching device, is a new circuit element, and must be characterized before it can be used in a practical manner by circuit designers. The purpose of this paper is to perform that task. Theotsis characterized in terms of both its static and dynamic parameters. A study is made of the blocking state and of the conducting state of theots. Experiments on switching, both from the blocking to the conductive state and vice versa, are discussed. Also included is a study of energy and charge switching requirements and the effect of pre-breakdown bias voltage and polarity reversals on the turn-on mechanism.The static and dynamic parameters are characterized in terms of temperature, device geometry and other parameters. It is shown that polarity reversals during the pre-breakdown period do not affect delay time and that pre-bias reduces delay time independently of polarity.
