## 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).
