Monday Abstracts Monday, October 22 Introduction to a few basic concepts in thermoelectricity Giuliano Benenti Center for Nonlinear and Complex Systems, Università degli Studi dell'Insubria, Via Valleggio 11, 22100 Como, Italy I will review fundamental aspects of heat to work conversion, including the phenomenological coupled charge and heat transport equations of non-equilibrium thermodynamics, the Onsager reciprocity relations, the figure of merit ZT for thermoelectric efficiency, the Curzhon-Ahlborn efficiency at maximum power, the Wiedemann-Franz law and Mott's formula. __________________________________________________________________________ Thermal Transport and Thermoelectric Coefficients Near the Anderson Transition and in 3-Terminal Molecular-Type Junctions (*) Yoseph Imry Weizmann Institute of Science (*) Patent application pending We start by reviewing thermal and thermoelectric linear transport, including the various coefficients the symmetry relations among them (Onsager) and what determines their magnitudes. Applications will be briefly mentioned along with the requirements on the above coefficients. Next, the Anderson localization transition will be considered at finite temperatures. This includes the electrical conductivity as well as the electronic thermal conductivity and the thermoelectric coefficients [1-3]. The latter becomes relatively large at low temperatures near the transition, its interesting critical behavior is found. A method for characterizing the conductivity critical exponent, an important signature of the transition, using both the conductivity and thermopower measurements, is outlined. Then, the thermoelectric transport through a molecular bridge (or a corresponding quantumdot arrangement) - a model nanosystem - will be discussed, with an emphasis on the effects of inelastic processes of the transport electrons caused by the coupling to the vibrational modes of the molecule. In particular it is found that when the molecule is coupled to a thermal bath of its own, which may be at a temperature different from those of the electronic reservoirs, a heat current between the molecule and the reservoir can be generated by the usual electric current. Expressions for the transport coefficients governing this conversion and similar ones are derived, and possible scenarios for increasing their magnitudes are outlined along with related semiconductor junction systems [4]. The latter interesting case of three terminals with two types of carriers presents novel possibilities. We shall conclude by demonstrating its advantage over usual two-terminal situations, for thermoelectric energy conversion [5]. [1] M. Cutler and N. F. Mott, Phys Rev. 181, 1336 (1969)
