【 摘 要 】

The time-dependent response of Ovonic devices to an electric potential ramp signal is analysed by means of an enhanced version of a previously published time-dependent charge- transport model proposed by the authors. Depending on the inevitable parasitics of the system, either stable or oscillating solutions are found according to the position of the load line. The model also allows for speculations on the potential of Ovonic materials in the design of high- frequency oscillating circuits close to the terahertz range.
