Moir superlattices—periodic orbital overlaps and lattice-reconstruction between sites of high atomic registry in vertically-stacked 2D layered materials—are quantum-active interfaces where non-trivial quantum phases on novel phenomena can emerge from geometric arrangements of 2D materials, which are not intrinsic to the parent materials. Unexpected distortions in band-structure and topology lead to long-range correlations, charge-ordering, and several other fascinating quantum phenomena hidden within the physical space between the (similar or dissimilar) parent materials. Stacking, twisting, gate-modulating, and optically-exciting these superlattices open up a new field for seamlessly exploring physics from the weak to strong correlations limit within a many-body and topological framework. It is impossible to capture it all, and the aim of this review is to highlight some of the important recent developments in synthesis, experiments, and potential applications of these materials.

莫尔超晶格——垂直堆叠二维层状材料中高原子登记位点之间的周期性轨道重叠和晶格重建——是量子活性界面，其中新现象上的非平凡量子相可以从二维材料的几何排列中出现，而不是母体材料的固有特性。能带结构和拓扑结构中的意外扭曲导致长程相关性、电荷排序和其他一些隐藏在（相似或不同）母体材料之间物理空间内的迷人量子现象。堆叠、扭曲、门调制和光激发这些超晶格开辟了一个新领域，可以从弱到无缝地探索物理学。强相关性限制在多体和拓扑框架内。不可能全部掌握，本综述的目的是突出这些材料的合成、实验和潜在应用方面的一些重要最新进展。
