Electrical switching in bulk samples of 0.15As-0.12Ge-0.73Te glass
Abstract
Switching in bulk samples of 0.15As-0.12Ge-0.73Te glass is caused predominantly by the thermal switching mechanism for near treshold applied voltages. Switching also occurred by the thermal mechanism even for applied voltages an order of magnitude above the threshold voltage of the sample. A constant voltage pulse was applied to the sample and the delay time and the electrical energy input to the sample during the delay time measured. A log-log plot of the energy input to the sample during a delay time of 1.00 s as a function of the electrode spacing on the sample's surface had a slope of approximately 1.6. For theoretical study of the thermal switching mechanism, a one-dimensional calculation of the heat balance equation with radial heat flow was made and the results of the calculation followed the same trends as the experimental data.
