Abstract

Measurements of thermal conductivity (λ) and thermal diffusivity (χ) of Se98 In2-χSnχ(χ=0,0.5,1,1.5) semiconducting glasses have been presented in this paper. The measured values of both λ and χ have been used to determine the specific heat per unit volume (pcp) of these glasses and in the Composition range of investigation. Both λ and χ are found to increase systematically with the addition of Sn. This compositional dependence behavior of λ and χ is attributed to the replacements of the original structural units by Se-Sn units. These new structural units increase the cohesive energy of the system and account for the observed increase in λ and χ. The type of bond, iono-covalent, which Sn makes with Se as it is incorporated in Se-In-Sn glass, is in support of our results.
