A Linear Thermoelectricity Theory for Thermoelectric Materials

physica status solidi (b), 2022
The governing equations of thermoelectricity are nonlinear in general. Herein, a first‐order linear theory of thermoelectricity for thermoelectric (TE) materials is presented, in which the Joule heating contribution is neglected in the energy balance equation as it is usually at least one order of magnitude smaller than the total thermal energy in TE ...

Nanostructured materials for thermoelectric applications

Chemical Communications, 2010
Recent studies indicate that nanostructuring can be an effective method for increasing the dimensionless thermoelectric figure of merit (ZT) in materials. Most of the enhancement in ZT can be attributed to large reductions in the lattice thermal conductivity due to increased phonon scattering at interfaces. Although significant gains have been reported,

Carrier Mapping in Thermoelectric Materials

MRS Proceedings, 2013
ABSTRACTThe application of micro-fourier transform infrared (FTIR) mapping analysis to thermoelectric materials towards identification of doping inhomogeneities is described. Micro-FTIR, in conjunction with fitting, is used as analytical tool for probing carrier content gradients.
