Abstract.

Electrical switching in germanium telluride glasses containing metallic atoms (Cu and Ag) has been investigated. All these glasses are found to exhibit memory switching. The switching fields of these glasses are compared with the thermal parameters evaluated from DSC studies and the results are explained on the basis of the thermal model. The composition dependence of the switching field and the thermal parameters show interesting variations at the critical compositions which correspond to the rigidity percolation and the chemical thresholds of these glasses.
