Abstract

Alternating differential scanning calorimetry measurements have been undertaken on the Ge15Te85-xInx (1 <= x <= 11) series of glasses. It is found that there is a marginal decrease in the glass transition temperature (T-g) in the composition range 1 <= x <= 3. Above x = 3, a monotonic increase is seen in T-g which indicates a continuous build-up in network connectivity and absence of any nanophase separation. The non-reversing heat flow (Delta H-NR) has been found to exhibit a broad trough between the compositions x = 3 and 7, which clearly indicates the presence of a thermally reversing window in Ge15Te85-xInx glasses in the composition range 3 <= x <= 7.
