TT: Fachverband Tiefe Temperaturen

TT 1: Tutorial: Thermoelectricity – Fundamental Aspects, Materials, Applications (joint session TT/TUT/MA)

Sunday, March 17, 2024, 16:00–18:10, H 1058

Thermoelectric effects have been discussed for several decades and have found widespread applications. Characteristic physical quantities are the efficiency, the figure of merit, ZT, and the power factor. In particular, increasing ZT has been the issue for many years. In recent developments, the focus has been on “unconventional” thermoelectric phenomena and materials: these include, in particular, transverse thermoelectric effects where the generated charge current is perpendicular to the temperature gradient, as can be observed, e.g., when applying a magnetic field (ordinary and anomalous Nernst effect). Transverse thermoelectricity can be found even without a magnetic field, e.g., in goniopolar materials (which have n- and p-type parts of the Fermi surface at the same time). – The Tutorial, jointly organized by the divisions MA and TT, will cover the basic physics of thermoelectricity, as well as discuss the question which materials are most useful for which applications, respectively. Attending the Tutorial thus will allow the non-experts in the field to fully appreciate the related presentations in the conference.
