S10: Thermoelectrics: From Nanoscale Fundamental Science to Devices


Register for EMA 2015 today


Approximately 40% of the primary energy produced world-wide is lost as waste heat, much of it at high grade. Thermoelectric materials have attracted increasing interest in this context since they are low cost, scalable, and flexible devices that enable energy conversion in the relevant temperature ranges. This symposium focuses both on (i) the fundamental science of relevant thermoelectric properties (i.e., Seebeck effect, electrical and thermal conductivity) and (ii) challenges and solutions for advanced thermoelectric materials and devices, including novel materials, measurements, bonding, ceramic processing, crystal chemistry, modeling, nanostructured materials, devices, and others.


Fundamental physics include phonon transport and interactions in solids, nanosystems and across interfaces. Topics including, but not limited to, coherent phonon transport, non-local phonon conduction around interfaces, phonon interference, the interplay between material structures and intrinsic phonon scattering mechanisms, and how these processes relate to the thermal conduction mechanisms in solids and across interfaces are encouraged. Problems encountered and solutions developed overlap with a broader spectrum of topics. This symposium encourages contributions from topics outside the traditional thermoelectrics research to cultivate exchange of ideas, especially on electrical and thermal properties. This symposium is a forum for discussing defect chemistry, conductivity, thermal conductivity optimization and applications for novel thermoelectrics.
