湿化学方法掺杂Na对多晶SnS热电性能的影响（英文）
|
摘要
SnS作为一种与SnSe特征结构相似且元素丰度更高的热电材料,受到越来越多的关注,但是其较低的本征载流子浓度限制了热电性能的提升.本工作利用了一种改进的化学共沉淀方法调节基体中Na~+含量来提高载流子浓度,进而提升了多晶SnS的热电性能.最大功率因子在873 K达到362μW m~(-1)K~(-2),高于目前关于多晶SnS的最高报道值.得益于提升的电输运性能以及较低的热导率, ZT值在873 K达到0.52.该工作为其他热电化合物的掺杂改性技术提供了新思路.
Tin sulfide(SnS) has analogous structural features to tin selenide(SnSe), but contains more abundant resources as compared with SnSe. SnS has elicited attention as a potential eco-friendly thermoelectric(TE) material. However,the intrinsic carrier concentration of SnS is very low, thereby hindering the performance improvement of the material. This study proposes that the TE properties of polycrystalline Nadoped SnS(synthesized through an improved chemical coprecipitation) can be significantly enhanced. The maximum power factor(PF) of 362 μW m~(-1) K-2 at 873 K was achieved,presenting a state-of-the-art value for the polycrystalline SnS.Considering the merits of the improved electrical properties and lower thermal conductivity of SnS, the highest ZT was up to 0.52 at 873 K even without intentional chemical doping.This study offers an effective approach for improving the PF to achieve high ZT in SnS. Hence, we expect that this new perspective can be extended to other dopants and broaden the scope of synthesis technology.
