With a large number of researches being conducted on two-dimensional (2D) materials, their unique properties in optics, electrics, mechanics, and magnetics have attracted increasing attention. Accordingly, the idea of combining distinct functional 2D materials into heterostructures naturally emerged that provides unprecedented platforms for exploring new physics that are not accessible in a single 2D material or 3D heterostructures. Along with the rapid development of controllable, scalable, and programmed synthesis techniques of high-quality 2D heterostructures, various heterostructure devices with extraordinary performance have been designed and fabricated, including tunneling transistors, photodetectors, and spintronic devices. In this review, we present a summary of the latest progresses in fabrications, properties, and applications of different types of 2D heterostructures, followed by the discussions on present challenges and perspectives of further investigations.
随着对二维（2D）材料进行的大量研究，它们在光学、电学、力学和磁学方面的独特性质已引起越来越多的关注。因此，将不同功能的二维材料组合成异质结构的想法自然而然地出现了，这为探索在单一二维材料或三维异质结构中无法实现的新物理现象提供了前所未有的平台。随着高质量二维异质结构可控、可扩展和程序化合成技术的迅速发展，已经设计并制造出了各种具有非凡性能的异质结构器件，包括隧道晶体管、光电探测器和自旋电子器件。在本综述中，我们总结了不同类型二维异质结构在制备、性质和应用方面的最新进展，随后讨论了当前面临的挑战以及进一步研究的前景。
