As a combination concept of a 2D material and a superlattice, two-dimensional superlattices (2DSs) have attracted increasing attention recently. The natural advantages of 2D materials in their properties, dimension, diversity and compatibility, and their gradually improved technologies for preparation and device fabrication serve as solid foundations for the development of 2DSs. Compared with the existing 2D materials and even their heterostructures, 2DSs relate to more materials and elaborate architectures, leading to novel systems with more degrees of freedom to modulate material properties at the nanoscale. Here, three typical types of 2DSs, including the component, strain-induced and moiré superlattices, are reviewed. The preparation methods, properties and state-of-the-art applications of each type are summarized. An outlook of the challenges and future developments is also presented. We hope that this work can provide a reference for the development of 2DS-related research.
作为二维材料和超晶格的组合概念，二维超晶格（2DSs）最近引起了越来越多的关注。二维材料在性质、维度、多样性和兼容性方面的固有优势，以及它们在制备和器件制造方面逐渐改进的技术，为 2DSs 的发展奠定了坚实的基础。与现有的二维材料甚至它们的异质结构相比，2DSs 涉及更多的材料和精细的结构，从而形成了具有更多自由度的新型系统，可以在纳米尺度上更精细地调控材料性质。本文综述了三种典型的 2DSs，包括组分、应变诱导和莫尔超晶格。总结了每种类型的制备方法、性质和最新应用。还展望了挑战和未来发展。我们希望这项工作能为 2DS 相关研究的发展提供参考。
