Promising candidates for thermoelectrics have been identified from systematic studies of the phase relations in ternary intermetallic phases. The potential of these candidates for thermoelectrics is restricted due to their large thermal transport. We apply four different strategies to decrease the thermal transport in these intermetallic phases: (a) synthesis of nanostructured CoSb3 and skutterudite-type La1-xCo4-yFeySb12 (0

通过对三元金属间相的相关系的系统研究，确定了热电学中有前途的候选材料。这些候选热电材料的潜力由于其大的热输运而受到限制。我们采用了四种不同的策略来减少这些金属间相的热输运：(a)合成纳米结构的CoSb3和滑石型的La1-xCo4-yFeySb12 (0
