Abstract

Heat can be directly converted into electricity via the thermoelectric effect in a device which has nomoving parts and no operational carbon footprint. More efficient thermoelectric materials are highlysought after as energy harvesting materials and as way to understand how charge and heat interact withone another. In addition to charge, electrons carry a purely quantum property known as spin. Under theinfluence of an applied temperature difference, certain “spintronic” materials generate spin-dependentpotentials useful for a host of applications. The interplay between spin and heat is described by the spinthermopower, a quantity we calculate and analyze for a few interesting systems.
