摘要BiS2基化合物构成了一个新的层状超导体家族。在这篇文章中，几个实验结果的超导电性和相关性质的BiS2家庭进行了审查。特别是，重点是在BiS2家庭的超导性和更高的超导转变温度的出现所需的条件：它表明，优化电子掺杂和晶体结构是重要的。此外，还简要介绍了超导与磁性共存以及超导与电荷密度波不稳定性之间的关系等几个显著特征。
Abstract BiS2-based compounds constitute a new family of layered superconductors. In this article, several experimental findings on the superconductivity and related properties of the BiS2 family are reviewed. In particular, the focus is on the conditions required for the emergence of superconductivity and higher superconducting transition temperature in the BiS2 family: it is shown that optimizing the electron doping and crystal structure are important. Further, a few notable characteristics such as the coexistence of superconductivity and magnetism as well as the relation between the superconductivity and chargedensity- wave instability are introduced in brief.
