Thermal conductivity, thermal diffusivity and specific heat of se98 In2-x snx (x = 0,0.5,1,1.5)‎ semiconducting glasses

Abstract EN

measurements of thermal conductivity (y) and theramal diffuivity (x) of Se98 In2-xSnx (x =0, 0.5,1,1.5) semiconducting glasses have been presented in this paper.

the measured values of both y and x have been used to determine the specific heat per unit volume (pcp) of these glasses and in the composition rane of investigation.

both y and x are found to increase systematically with the addition of.

this compsitional dependence behavior of y and x is attibuted to the replacement of the original structural units by Se_ Sn units.

these new structural units increase the cohesive energy of the system and accout for the observed increase in y and x.

the type of bond, iono-covalent, which Sn makes with Se as it is incorported in Se-In-Sn glass, is in support of our result.
