The Thermoelectric, Galvanomagnetic and Thermomagnetic Effects of Monovalent Metals

A Theory of the thermoelectric effects and transverse galvano- and ther-momagnetic effects of monovalent metals is described on a model of general spherical energy band. Boltzmann's equation is solved by a variational method, and whence we get a formula of thermoelectric power which shows the possibility of positive thermoelectric power at high temperatures but not at low temperatures. The effect of the Umklapp processes on the time of relaxation at high temperatures is also investigated. Our simple model can derive the negative Ettingshausen and Ettingshausen-Nernst coefficients of noble metals at high temperatures.
