摘要

研究了Ag/sub 9/TlTe/sub 5/和AgTlTe的热电性能。从室温到约700 K，铊化合物的导热系数极低，约为0.25 Wm/sup -1/K/sup -1/。铊化合物表明ZT值非常高;其中Ag/sub 9/TlTe/sub 5/在700 K时ZT值最高，为1.23。Ag/sub 9/TlTe/sub 5/是一种独特的材料，具有极低的导热系数和相对较低的电阻率。

Ag/sub 9/TlTe/sub 5/ and AgTlTe: high ZT materials with extremely low thermal conductivity

We have studied the thermoelectric properties Ag/sub 9/TlTe/sub 5/ and AgTlTe. The thallium compounds have extremely low thermal conductivities around 0.25 Wm/sup -1/K/sup -1/ from room temperature to about 700 K. The thallium compounds indicate very high ZT values; especially the highest ZT value of Ag/sub 9/TlTe/sub 5/ is 1.23 obtained at 700 K. Ag/sub 9/TlTe/sub 5/ is a unique material combining extremely low thermal conductivity and relatively low electrical resistivity.
