摘要：

二维过渡金属硫族化合物具有独特、优异的电学和力学性能，已被广泛应用于基础研究以 及电子、自旋电子、光电子、能量收集捕获和催化等领域当中。然而，二维过渡金属硫族化合物在 苛刻的条件下不稳定，并且在环境中极易降解，这限制了其在大多数领域的应用。在本篇综述中， 我们总结了二维过渡金属硫族化合物环境稳定性研究的最新进展，包括最新的生长方法、稳定性 的基本机制以及保护二维过渡金属硫族化合物材料免受老化和性能衰退的方法。通过从生长过程 中分析影响二维过渡金属硫族化合物稳定性的关键因素，我们对优化生长方法以提高其稳定性进 行了回顾。最后，我们展望了生长稳定二维过渡金属硫族化合物的指导方法，这也为制备、设计 其他先进功能材料以及相应异质结结构带来可能。

Abstract:

Two-dimensional (2D) transition metal dichalcogenides (TMDCs) with a unique unity of favorable electronic and mechanical properties have been developed for fundamental studies and applications in electronics, spintronics, optoelectronics, energy harvesting and catalysis. However, as they are unstable under harsh conditions, and prone to degradation in the ambient environment, most TMDCs applications are limited. In this review, we analyze the recent advances in the research of environmental stability in TMDCs, covering the latest growth methods, the fundamental mechanisms for stability and kinds of routes to protect 2D TMDCs materials from aging and deterioration. By analyzing key factors that affect TMDCs stability from the growth process, we present a short review of optimizing growth methods for improving the stability of TMDCs. Finally, by providing insights into existing factors, this review is expected to guide the growth of stable TMDCs, which could lead to a new potential approach to growing advanced materials and designing more unexplored heterostructures. 

Key words: two-dimensional materials, transition metal dichalcogenides, stability, vacancy
