In this study, we have studied the effect of elements Ag, Cd, and Sn as chemical modifiers on some thermal transport properties (thermal conductivity, diffusivity, and specific heat per unit volume) of amorphous Se. Concurrent measurements of thermal transport properties such as effective thermal conductivity (λe), thermal diffusivity (χe), and specific heat per unit volume (ρC v) are used at room temperature for twin pellets of pure Se- and Se-based binary Se98M2 (M = Ag, Cd, and Sn) alloys using transient plane source technique. We have also determined the thermal inertia I T using the experimental values of thermal conductivity and specific heat per unit volume for present amorphous alloys. The increasing sequence of measured thermal transport properties is also discussed.
