Quantum materials have attracted much attention in recent years due to their exotic and incredible properties. Among them, van der Waals materials stand out due to their weak interlayer coupling, providing easy access to manipulating electrical and optical properties. Many fascinating electrical, optical, and magnetic properties have been reported in the moiré superlattices, such as unconventional superconductivity, photonic dispersion engineering, and ferromagnetism. In this review, we summarize the methods to prepare moiré superlattices in the van der Waals materials and focus on the current discoveries of moiré pattern-modified electrical properties, recent findings of atomic reconstruction, as well as some possible future directions in this field.
近年来，量子材料因其奇异且令人难以置信的特性而备受关注。其中，范德华材料因其层间耦合较弱而脱颖而出，这使得操控其电学和光学性质变得容易。在莫尔超晶格中已经报道了许多引人入胜的电学、光学和磁学性质，例如非常规超导、光子色散工程和铁磁性。在这篇综述中，我们总结了在范德华材料中制备莫尔超晶格的方法，并重点关注莫尔图案修饰的电学性质的当前发现、原子重构的最新研究结果以及该领域一些可能的未来发展方向。
