DS 20: Focus Session: Organic-based Hybrid Thermoelectrics I

Mittwoch, 18. März 2020, 09:30–11:00, CHE 89

Waste heat at moderate temperatures of around 100C constitutes an energy source of enormous potential for recuperative technologies such as themoelectrics. By their inherently low thermal conductivity, possibility for p- and n-type doping, sustainability as well as low-cost processing, organic semiconductors have entered the focus of interests in recent years. In addition, the strong electron-phonon interaction in this material class results in a wealth of new phenomena ranging from phonon-drag effects to electronic correlations. However, a comprehensive picture of the microscopic mechanisms governing the thermoelectric properties as well as advanced hybrid material concepts are necessary to further enhance their thermoelectric figure-of-merit and, thereby, to pave the way towards first technologically relevant implementations.

This focus session aims for bringing together material scientists, chemists and physicists working in the fields of material synthesis, thin film preparation, doping of organic semiconductors, in-depth thermoelectrical characterizations as well as theoretical modelling. Only the concerted approach by the various disciplines will allow for a successful transformation of academic research into technologically relevant applications. Thus, this focus session will also provide a suited platform for an intense informational exchange as well as for initiating possible future collaborations between the participating groups.

Organizers: Manfred Albrecht (Universität Augsburg), Wolfgang Brütting (Universität Augsburg), Jens Pflaum (Universität Würzburg)
