摘要

Alternating differential scanning calorimetric (ADSC) studies and electrical switching experiments have been undertaken on Al15Te85-xSix (2 <= x <= 12) system of glasses. These glasses are found to exhibit two crystallization reactions (T-c1 and T-c2), for compositions with x < 8. Above x = 8, a single-stage crystallization is seen. Further, a trough is seen in the composition dependence of non-reversing enthalpy (Delta H-NR), based on which it is proposed that there is a thermally reversing window in Al15Te85-xSix glasses, in the composition range 4 <= x <= 8. Electrical switching studies indicate that Al15Te85-xSix glasses exhibit a threshold type electrical switching at ON state currents less than 2 mA. Further, the switching voltages are found to increase with the increase in silicon content. It is interesting to note that the start (x = 4) and the end (x = 8) of the thermally reversing window are exemplified by a kink and a saturation in the composition dependence of switching voltages, respectively.
