Utilizing Phase Separation Reactions for Enhancement of the Thermoelectric Efficiency in IV–VI Alloys

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

In recent years, demands for energy efficiency have motivated many researchers
worldwide to seek innovative methods capable of enhancing the efficiency of the
thermoelectric energy conversion of heat to electricity. Since the dimensionless
thermoelectric figure of merit ZT (=𝛼2𝜎T/𝜅, where 𝛼 is the Seebeck coefficient,
𝜎 is the electrical conductivity, 𝜅 is the thermal conductivity, and T is the absolute
temperature) can be regarded to be proportional to the thermoelectric efficiency
for a given temperature difference, materials improvements in this direction
include either electronic optimization methods for maximizing the 𝛼2𝜎 product
or phonons scattering methods for minimizing the thermal conductivity (the
denominator of ZT).
