Abstract
A Seebeck effect thermoelectric cooler, operative at cryogenic temperatures, in which two materials having different Seebeck coefficients are in electrical contact so that current flow thereacross cools the junction. One or both of the materials comprise a metal-insulator transition material characterized by doping, alloying, or other means to be just slightly metallic so that electrical resistance becomes lower at lower temperatures, but the Seebeck coefficient does not decline at lower temperatures, as would be the case if the material were allowed to become fully metal-like.
