Although the 1T' phase is rare in the transition metal dichalcogenides (TMDCs) family, it has attracted rapid growing research interest due to the coexistence of superconductivity, unsaturated magneto-resistance, topological phases etc. Among them, the quantum spin Hall (QSH) state in monolayer 1T'-TMDCs is especially interesting because of its unique van der Waals crystal structure, bringing advantages in the fundamental research and application. For example, the van der Waals two-dimensional (2D) layer is vital in building novel functional vertical heterostructure. The monolayer 1T'-TMDCs has become one of the widely studied QSH insulator. In this review, we review the recent progresses in fabrications of monolayer 1T'-TMDCs and evidences that establish it as QSH insulator.

单层 1T'-TMDC 中的量子自旋霍尔态

虽然 1T' 相在过渡金属二硫属化物 (TMDCs) 家族中很少见，但由于超导性、不饱和磁阻、拓扑相等的共存，它引起了快速增长的研究兴趣。 其中，量子自旋霍尔 (QSH)单层1T'-TMDCs中的状态特别有趣，因为它具有独特的范德华晶体结构，在基础研究和应用中具有优势。例如，范德华二维 (2D) 层对于构建新型功能性垂直异质结构至关重要。单层1T'-TMDCs已成为广泛研究的QSH绝缘体之一。在这篇综述中，我们回顾了单层 1T'-TMDC 制造的最新进展，以及将其作为 QSH 绝缘体的证据。
