ABSTRACT:
A thermoelement (leg) of a thermocouple for use in peltier heating or generation of power by the Seebeck effect including a plurality of interleaved films wherein compositions of neighboring films are selected to create Kapitza boundaries between the films such as to reduce thermal conductivity but provide adequate electrical conductivity. The plurality of interleaved films includes a semiductor with suitable doping to establish required extrinsic conductivity and metals having dissimilar lattices such as aluminum and tungsten abutting one another. The practical number of films in the composite to establish the effect is ten. A preferred thickness of the films is less than twenty thousand Angstroms.
