莫尔超晶格和莫尔激子的最新进展，例如量子发射阵列，低能平带和莫特绝缘子，迅速吸引了光电子学，材料和能量研究领域的关注。层间扭转变成自由度，自由度改变了材料系统的特性，而莫尔激子的实现也提供了制造人造激子晶体的可行性。而且，莫尔激子在各种外部条件(包括空间极化，交替偶极和门相关性)的调节下均表现出许多令人兴奋的特性。所有这些都与纳米光子学和量子信息中的应用有关。但是，理论发展的滞后和加工技术的低效率极大地限制了莫尔超晶格应用的潜力。在这篇综述中，我们系统地总结和讨论了莫尔超晶格和莫尔激子的最新进展，并分析了当前的挑战，并提出了相关建议。毫无疑问，莫尔超晶格进一步的研究将导致应用领域的突破，并引发传统固态物理学和材料科学领域的改革与创新。

Comments:
Moiré superlattice is a periodic pattern formed by the overlap of two or more lattices with slightly different lattice constants. In the context of twisted van der Waals heterostructures, the Moiré superlattice is created by the rotation of two graphene or transition metal dichalcogenide (TMD) layers with respect to each other.
Moiré Excitons are light-emitting particles that are associated with Moiré superlattice in twisted van der Waals heterostructures. These excitons are created by the interaction between electrons and holes in the overlapped lattice, and they are highly localized in the Moiré pattern.
Moiré superlattices and Moiré Excitons have gained a lot of attention in the field of condensed matter physics and materials science due to their unique properties and potential applications in optoelectronics and photonics. For example, the presence of Moiré Excitons in twisted van der Waals heterostructures can significantly enhance the light emission efficiency and stability, which makes them suitable for use in optoelectronic devices such as OLEDs and LEDs.
In conclusion, Moiré superlattice and Moiré Excitons in Twisted van der Waals Heterostructures are important research areas that hold great potential for the development of advanced materials and devices.
