Abstract
The thermal conductivity of chalcogenide binary Se-Te and ternary Se-Te-Cu alloys (polycrystalline and amorphous) has been investigated in stationary conditions within the temperature range 7-315 K. Non-typical low-temperatur e sharp maximum at about 14 K in the crystalline samples has been observed. A hysteresis has appeared in the amorphous sample with 5% Cu content. Qual itative analysis of the measurement results based on the Boltzmann equation has been presented. (C) 2001 Elsevier science Ltd. All rights reserved.
