Abstract
Time-dependent electrical resistivity measurements are carried out on As-Te-Se glasses at different fixed pressure using the Bridgman anvil system. At pressures, p < 18 kbar, the variation of electrical resisti vity with time exhibits an exponential behavior, and at pressures p > 18 kbar it shows a stretched exponential behavior. This behavior can b e explained on the basis of critical thresholds and fractal dimension of the network glasses.
