Description

The threshold switching characteristics of amorphous NbO<inf>x</inf> thin films is investigated with particular emphasis on temperature dependence of the switching characteristics. Threshold switching in this material is believed to result from a thermally-induced insulator-metal-transition (IMT) induced along a filamentary path by local Joule heating. Increasing the operating temperature is shown to lead to a reduction in the resistance of the high-resistance state and to a reduction in the...[Show more]

dc.description.abstractThe threshold switching characteristics of amorphous NbO<inf>x</inf> thin films is investigated with particular emphasis on temperature dependence of the switching characteristics. Threshold switching in this material is believed to result from a thermally-induced insulator-metal-transition (IMT) induced along a filamentary path by local Joule heating. Increasing the operating temperature is shown to lead to a reduction in the resistance of the high-resistance state and to a reduction in the threshold switching voltage. These results are discussed in relation to the transport properties of NbO<inf>x</inf> and the IMT switching model.
