Realizing the full potential of any materials system requires understanding and controlling disorder, which can obscure intrinsic properties and hinder device performance. Here we examine both intrinsic and extrinsic disorder in two-dimensional (2D) materials, in particular graphene and transition metal dichalcogenides (TMDs). Minimizing disorder is crucial for realizing desired properties in 2D materials and improving device performance and repeatability for practical applications. We discuss the progress in disorder control for graphene and TMDs, as well as in van der Waals heterostructures realized by combining these materials with hexagonal boron nitride. Furthermore, we showcase how atomic defects or disorder can also be harnessed to provide useful electronic, optical, chemical and magnetic functions.

2D材料范德华力异质结构的无序

要实现任何材料系统的全部潜力,需要了解和控制混乱,这会掩盖其固有特性并阻碍器件性能。在这里,我们研究了二维(2D)材料(特别是石墨烯和过渡金属二卤化碳(TMDs))中的内在和外在无序。最小化无序性对于实现2D材料中的所需特性以及提高设备性能和实际应用的可重复性至关重要。我们讨论了石墨烯和TMD的无序控制方面的进展,以及通过将这些材料与六方氮化硼结合在一起实现的范德华异质结构。此外,我们展示了如何利用原子缺陷或无序来提供有用的电子,光学,化学和磁性功能。
