Outline of Final Research Achievements

Thermoelectric (TE) generation is one of thean attractive technologies technology because it can convert waste heat directly into electricity. Mg2Si has been recognized as a good environmentally benign TE materialg. Focusing on systems the that are appropriate systems for automotive applications, TE power generation modules should have sufficient thecapabilities capability to work operate well even under conditionsconditions during operations. In order to realize a practical TE power generation module, better understanding of the thermoelectric and mechanical properties of the TE materials is essential to enable facilitate the structural design of TE power generators. Theoretical studies are important to achieve a thorough understanding of the electronic and carrier transport properties of Mg2Si to enable the design of high-performance Mg2Si-based materials. The results obtained within this project could provide well-defined understanding for above mentioned development issues.
