Abstract
Abstract
After Onsager the thermopower of a material is related to the ratio either of two transport coefficients or of the gradients of the electrochemical potential of the electrons and the temperature. In metals the potential is a unique function of the temperature and this ratio can be replaced by the differential quotient, a function obtainable from the density of states of the metal as illustrated on a thermopower isotherm of Nb–Mo alloys.
