Outline of Final Research Achievements

A basic research has been done for development of high-performance thermoelectric materials used for thermoelectric power generation, which can produce electric power from a huge amount of waste heat in the world. To get a guiding principle increasing thermoelectric performance of structurally complex materials, it has been tried to establish how to understand the electronic structure and to control the thermoelectric properties of the solids from the structure and electronic states of the clusters, which are the structural units of them. The vision to understand the origin of high-performance electronic structure and to develop the high-performance materials could be obtained.
