在这项研究中，我们已经合成了掺杂锌（Zn）的SnSe，并研究了Zn掺杂对SnSe的热电性能的影响。结果表明，Zn0.01Sn0.99Se在873 K时具有较高的热电优值（ZT），ZT为0.96，比纯SnSe的ZT（0.68）提高了41%.该值是p型多晶掺杂SnSe材料所报道的最高值，这是由于来自高电导率和增强的塞贝克系数的增加的功率因数而引起的。(C)2016 Acta Materialia Inc由Elsevier Ltd.出版。保留所有权利。
In this study, we have synthesized SnSe doped with zinc (Zn) and investigated the effect of Zn doping on the thermoelectric properties of SnSe. The results demonstrate that a high thermoelectric figure of merit (ZT) of 0.96 at 873 K is obtained for Zn0.01Sn0.99Se, which is 41% higher than that of pure SnSe (ZT = 0.68). The value is the highest value reported for p-type polycrystalline doped SnSe materials, which arises from the increased power factor coming from a high electrical conductivity and an enhanced Seebeck coefficient.
