Thermal Conductivity Mechanisms in Compressed Thermoelectric Materials Based on A4B6 Compounds
Journal Title: Фізика і хімія твердого тіла - Year 2018, Vol 19, Issue 3
Abstract
The factors influencing the value of the thermal conductivity coefficient of thermoelectric materials based onlead telluride obtained by powder pressing method have been analyzed. The model is presented and its parameters aredefined, which explains qualitatively and quantitatively the temperature dependences of the thermal conductivitycoefficient of PbTe and PbSnAgTe.
