Abstract

A nonlinear and nonlocal phenomenological theory of energy and electric transport in anisotropic media under extreme temperature conditions is proposed. The anisotropy of thermo-emf can be created in cubic crystals under conditions of large temperature gradients. Therefore cubic semiconductors can be used as materials for anisotropic thermoelements. The thermoelectric voltage generated in nonlinear anisotropic thermoelement strongly increase with decrease of the semiconductor´s film thickness. Nonlinear anisotropic thermoelements can be used as microminiature energy converter.
