STATIC ENERGY CONVERSION STUDIES,
Abstract
The general concept of the solid-state Nernst effect generator is considered; the efficiency is calculated in terms of the material's figure of merit ZNT, defined analogously to the figure of merit for thermoelectric materials. The ideal Nernst material would be a semimetal with zero Hall coefficient. The theoretical value of ZNT is limited by the phonon thermal conductivities, provided that the product of the magnetic field and carrier mobility (in lab units) is greater than one billion, otherwise, the finite field is the limiting factor. The optimum geometry of a Nernst generator is considered from the point of view of conserving magnetld volume as well as obtaining the highest possible output power at convenient voltages. (Author)
