The multi-component quaternary materials of the Se78-xTe20Sn2Bix (x = 0, 2, 4, 6) chalcogenide glasses system were synthesized with varying bismuth (Bi) composition by using a melt quenching technique. The thermal transport properties (effective thermal conductivity, diffusivity, and specific heat per unit volume) of the glasses were determined using the transient plane source (TPS) technique at room temperature. The TPS measurements found ...
