| Research Abstract |
We studied the possibility of high performance thermoelectric materials on guest-ordering clathrate compounds, that have several kinds of guest atoms and each kinds of guest atoms is filled in different kinds of cages, respectively. Then, a smaller size of guest atom is in a smaller cage and a larger size of guest atom is in a larger cage. In the theoretical study, we calculated guest size dependence for the electronic structure and the Seebeck coefficient by using the calculated band structure. In the experimental study, we tried to synthesize the guest-ordering clathrate compounds and measured the thermoelectric properties of obtained sample.
