Outline of Final Research Achievements

Recently, extensive studies on thermoelectric conversion have been performed toward practical usage on thermoelectric materials which can directly convert from waste heat into electrical energy. In this research project, we synthesized high-performance new materials through band structure engineering, measured the thermoelectric properties, and evaluated the physical properties from theoretical point of view toward better understanding physics behind materials. We found that Sb-based Zintl compounds and MoSi2-type Al6Re5Si4 compounds are both attractive for new thermoelectric materials.
