Abstract

The present paper reports a comparative study of some thermophysical properties (thermal conductivity, thermal diffusivity, thermal effusivity, and specific heat per unit volume) for \(\mathrm{{Se}}_{80}\mathrm{{Te}}_{20}\) and \(\mathrm{{Se}}_{80}\mathrm{{Te}}_{10}\mathrm{{M}}_{10}\) (Cd, In, and Sb) alloys. The transient plane source technique is used for this purpose. The thermal conductivity is highest for \(\mathrm{{Se}}_{80}\mathrm{{Te}}_{10}\mathrm{{In}}_{10}\) as compared to the other ternary alloys. This is explained in terms of the thermal conductivity of additive elements Cd, In, and Sb. The composition dependence of the thermal diffusivity and specific heat per unit volume is also discussed.
