| Outline of Final Research Achievements |
We fabricated both p- and n-type segmented thermoelectric elements using group-IV-element (Sn, Ge, Si)-based clathrate compounds. The segmented elements had mechanical strength enough to withstand device processing and had little contact electrical resistance. Power generation modules fabricated using them worked normally. The obtained power generation characteristics almost agreed with the estimation value from the thermoelectric properties of the constituent materials. We also developed Sn-based type-II clathrate sintered samples having high thermoelectric performance.
