S9: Direct Thermal-to-Electrical Energy Conversion Materials and Applications



Significant advances in direct thermal-to-electrical energy conversion materials have pushed these materials into new applications for solid-state energy harvesting or cooling. This symposium will highlight a combination of new ideas, new materials and device concepts by focusing on novel processing and synthesis methods, materials, technologies, and applications related to direct thermal-to-electric energy conversion. The symposium will focus specifically on thermoelectrics and thermionics and emphasize thermal, electrical, and mechanical properties of new materials and processing of those materials into device structures. It also will highlight material and device design innovations that lead to higher efficiency thermal-to-electric energy conversion technologies.


The symposium will include theoretical studies of material transport properties, band structure, crystal chemistry, thermodynamic analysis, and energy transfer. Experimental efforts will include new capabilities in solid-state synthesis, bulk materials, thin films, superlattices, and nanostructured materials, including recent advances in thermoelectric nanocomposites (nanomaterials or inherent nanostructures in bulk thermoelectric material matrices). It will also highlight advances in the use of spark plasma sintering to develop high performance thermoelectric materials. New developments in material property and device performance material property and device performance measurements and metrology will also be presented.
