Creation of a superlattice structure composed of Bi-Te thermoelectric nanoparticles for highly-efficient flexible thermoelectric devices

我们成功地合成了热电材料(TE)、BiSb-Te和Zn-Sb纳米粒子(NPs)。然后，由这些TE NPs组成的高阶结构(超晶格结构)可以被制造出来。(1)建立了单相(Bi，Sb)_2Te_3纳米线的合成方法；(2)采用湿化学法合成了由(Bi，Sb)_2Te_3纳米线组成的高阶结构，并对其TE性能进行了测试；(3)提出了一种制备(Bi，Sb)_2Te_3纳米线的方法并测试了其TE性能。

We successfully synthesized thermoelectric (TE) Bi-Sb-Te and Zn-Sb nanoparticles (NPs). Then, higher-order structures superlattice structures) composed of those TE NPs as building blocks could be fabricated. In consequence, we obtained the following results: (1) A synthesis method for single-phase (Bi,Sb)2Te3 nanowires (NWs) was developed; (2) Higher-order structures composed of (Bi,Sb)2Te3 NWs were created using wet-chemical processes and their TE properties were measured; (3) a synthesis method for ZnSb NPs was developed and their TE properties were measured.
