  • Abstract
    This paper describes experiments on threshold switching of Ge2Sb2Te5 (GST). In all the experiments, triangle current pulses are applied to study the threshold switching. The results have been presented and analyzed. Ovonic Threshold Switching (OTS) is further proved exist in threshold switching of GST. The low resistance of GST shown in threshold switching can be explained by the unstable filament which is formed under high electric field.
