Measurement of the Electrical and Thermal Conductivity Coefficients of As2Se3-As2Te3 Glassy Alloys

  • Chapter

Abstract

Eight alloys of general formula AsSe1 5−xTex(0.0 ⩽ x ⩽ 1.15)were prepared in the glassy state. The coefficients of thermal and electrical conductivity of the eight alloys were measured in a range of temperature up to the glass transformation temperature Tg for these glasses. The obtained results revealed the contribution of electrons is much less than that of phonons to the thermal conductivity. The increase of Te-content leads to monotonic increase of σ. The thermal conductivity decreases to a certain minimum (at 30 atm.% Te & Se) and then increases. This behavior can be attributed to a change of the number of scattering centers due to the dissolving of Te atoms or Se atoms in the amorphous As-Se-Te alloys.
