Title: Density variations in thermoelectrics

Abstract

Equations are solved to give the variations in temperature, density, and potential, when a solid has electrical currents, heat currents, and particle diffusion. Solutions are presented in one dimension for currents down a bar. These solutions are used to calculate the efficiency of a thermoelectric refrigerator, which is optimized to give the coefficient of performance (COP). The COP depends upon the temperature difference {delta}T, but does not depend upon the density difference {delta}n between the two ends of the bar. (c) 2000 American Institute of Physics.
