发现二维（2D）分层的Mosi $ _2 $ n $ _4 $和WSI $ _2 $ _2 $ n $ _4 $，没有2020年化学蒸气沉积的3D父母，这激发了2D MA $ _2 $ _2 $ _2 $ _2 $ _2 $ _2 $ _4 $系统的研究，这是由于其结构上的复杂性和多样性和多样性以及多样性的物质和杂物性和杂物性和杂物性和杂物性和杂物为物质所致。在这里，提出了有关此2D MA $ _2 $ z $ _4 $ family的最新进展的全面概述。从描述新兴单层MA $ _2 $ z $ _4 $的独特三明治结构特性开始，我们总结并解剖其多功能特性，包括机械，压电，热运输，电子，电子，光学/光电和磁性。还详细阐述了通过应变工程，表面功能化和分层策略可调节性的性能。然后对晶体管，光催化剂，电池和气体传感器应用2D MA $ _4 $应用2D MA $ _4 $的理论和实验尝试或进步进行了审查，以显示其在广阔领域的潜在应用。我们进一步讨论了新的机会，并为这个新兴的2D家庭提供了前景。预计该概述将指导2D MA $ _2 $ z $ _4 $的进一步理解和探索。
The discovery of two-dimensional (2D) layered MoSi$_2$N$_4$ and WSi$_2$N$_4$ without knowing their 3D parents by chemical vapor deposition in 2020 has stimulated extensive studies of 2D MA$_2$Z$_4$ system due to its structural complexity and diversity as well as versatile and intriguing properties. Here, a comprehensive overview on the state-of-the-art progress of this 2D MA$_2$Z$_4$ family is presented. Starting by describing the unique sandwich structural characteristics of the emerging monolayer MA$_2$Z$_4$, we summarize and anatomize their versatile properties including mechanics, piezoelectricity, thermal transport, electronics, optics/optoelectronics, and magnetism. The property tunability via strain engineering, surface functionalization and layered strategy is also elaborated. Theoretical and experimental attempts or advances in applying 2D MA$_2$Z$_4$ to transistors, photocatalysts, batteries and gas sensors are then reviewed to show its prospective applications over a vast territory. We further discuss new opportunities and suggest prospects for this emerging 2D family. The overview is anticipated to guide the further understanding and exploration on 2D MA$_2$Z$_4$.
