Thermoelectric Effects: Basic Aspects, Boltzmann Theory, Onsager Relations — •Arthur Ernst — Max-Planck-Institut für Mikrostrukturphysik, Halle — Wilhelm-Ostwald-Institut für Physikalische und Theoretische Chemie, Universität Leipzig

Thermoelectric phenomena which involve the conversion between thermal and electrical energy and provide a method of heating and cooling materials are expected to play an important role in meeting the energy challenge of the future. In my talk I shall present basic aspects of the microscopic theory for thermoelectricity. First, I discuss the basic definition of the thermoelectric heat. Then I present a short overview of non-equilibrium thermodynamics and the microscopic theory of the electronic transport. Further I review several approaches to describe thermoelectric properties, present the state of the art in the understanding the thermoelectric phenomena, and conclude my talk with some remarks on future prospects of the field.
