摘要:

自2012年以来,层状Bi硫族化合物作为一种新的层状超导体家族引起了人们的广泛关注。层状铋硫族化合物由于其丰富的晶体结构和组成元素,在新的物理和化学领域的发展及其作为功能材料的应用一直是人们所期待的。最近,据透露,层状Bi硫属化物可以显示出相对较高的热电性能(ZT = 0.36在LaOBiSSe在~650 K)。在这里,我们展示了Bi-硫族化合物家族的晶体结构变化及其热电性能。最后,在实验和理论的基础上,讨论了提高热电性能的可能策略。

英文摘要:

The layered Bi-chalcogenide compounds have been drawing much attention as a new layered superconductor family since 2012. Due to the rich variation of crystal structure and constituent elements, the development of new physics and chemistry of the layered Bi-chalcogenide family and its applications as functional materials have been expected. Recently, it was revealed that the layered Bi chalcogenides can show a relatively high thermoelectric performance (ZT = 0.36 in LaOBiSSe at ~650 K). Here, we show the crystal structure variation of the Bi-chalcogenide family and their thermoelectric properties. Finally, the possible strategies for enhancing the thermoelectric performance are discussed on the basis of the experimental and the theoretical facts reviewed here.
