Role of Capacitive Discharge Energy in the Switching of Semiconducting Glasses

Incorporation of capacitive discharge energy in the heat equation yields results consistent with some aspects of the observed behavior of threshold switching devices not only for the case in which all points on the $V-I$ curve are accessible, but also for the case in which abrupt switching at constant current is observed. The type of switching displayed by a given device is material dependent. We present a relationship for the prediction of device behavior.
