Toward a First-Principles Determination of Transport Coefficients

Chapter
Part of the Fundamental Materials Research book series (FMRE)

Abstract

The efficiency of a thermoelectric device depends on its geometrical design and on the transport coefficients of the material that constitutes the active thermoelements. The figure of merit of the material
$$ Z = \frac{{\sigma S^2 }} {\kappa } $$
(1)
is an expression involving the electrical conductivity a, the thermopower or Seebeck coefficient Sand the thermal conductivity κ. This quantity that has units of inverse temperature is the key to determine if a particular material has potential for thermoelectric applications.
