A continuum theory of thermoelectric bodies and effective properties of thermoelectric composites [PDF]

arXiv, 2011
We develop a continuum theory for thermoelectric bodies following the framework of continuum mechanics and conforming to general principles of thermodynamics. For steady states, the governing equations for local fields are intrinsically nonlinear.
