Elastic properties of As-Sb-Se glasses

Abstract

Results of measurement of elastic modulii on As-Sb-Se glasses are reported and their composition dependence discussed. The Young's and the shear modulii lie in the range of 170-210 and 65-80 kb respectively. These values are typical of chalcogenide glasses. For (As, Sb)40Se60 glasses, the modulii increase monotonically with increasing Sb2Se3 content. The observed composition dependence of the modulii for the Asx Sb15Se85 -x glasses is examined in terms of the chemically ordered structural units in the glasses. © 1984 Indian Academy of Sciences.
