Prediction of chalcogenide glassy phase diagrams

A recently formulated approach to constraint counting theory of glasses [Phys. Rev. B 60 (1999) 18599] in combination with a simple rule to estimate chemical order in a glassy alloy, predicts the phase diagram of a few ternary chalcogenide glass systems. This approach is found to be more accurate when compared with other prominent methods used for predicting glassy phase diagrams, based on the criterion that adjustable parameters be minimal.
