Effect of Freezing Conditions on the Thermoelectric Properties of BiSbTe3 Crystals

Abstract

The thermoelectric parameters α, 1/ρ, and 1/(K−K_e) of oriented polycrystals increase as the freezing rate decreases and as the temperature gradient in the liquid at the interface increases. The effects are primarily attributed to the variation in the degree of microsegregation produced in the crystals as a function of the freezing conditions.
