在5-310K温度范围内，研究了Sn替代对化合物Zn1-xSn沁b3的低温热电性能的影响。研究结果表明相对于无掺杂的Zn4Sb3，（Zn1-xSb3（x≠0）的低温热导率明显降低，并且随着Sn掺杂含量的增加而不断降低。实验结果也发现，掺杂Sn后化合物的直流电阻率和热电势都减小，且随着Sn掺杂量的增加而不断减小。

In this paper, the effects of Sn substitution of Zn on thermoelectric properties of （Zn1-xSnx）4Sb3 were studied at the temperatures from 5K to 310IC The results showed that low-temperature thermal conductivity of the doped β-（Zn1-xSnx）4Sb3 （x≠0） reduced remarkably as compared to that of Zn4Sb3, and decreased monotonously with increasing Sn content x. Meanwhile, DC electrical resistivity and thermopower of the doped compounds became smaller than that of un-doped Zn4Sb3, and decreased monotonously with increasing Sn content x.
