Analysis of composition dependence of some thermal transport properties in glassy Se_(80-x)Te_(20)Sn_x (0 ≤ x ≤ 10) alloys using transient plane source measurements

摘要

In the present work, we have studied simultaneous measurements of thermal transport properties (effective thermal conductivity, diffusivity, specific heat per unit volume, thermal inertia I_T) of glassy Se_(80-x)Te_(20)Sn_x (0 ≤ x ≤ 10) system using their twin pellets. The glassy system is prepared under a load of 5 tons and measurements have been made at room temperature using Transient Plane Source (TPS) technique. The composition dependence of the thermal transport properties of given glassy system is also discussed.
