Abstract: The multi-component quaternary materials of the Se_78-xTe₂₀Sn₂Bi_x (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 that adding Bi content into the glasses suppressed the effective thermal conductivity in the parent Se₇₈Te₂₀Sn₂ glass.
