2D Moiré superlattice materials: Synthesis, properties and applications

Moiré materials, as a type of superlattice material with unique structures and properties, have attracted extensive attention and research in recent years. They are formed by the overlap of two or more two-dimensional (2D) lattices with small rotational or lattice constant differences, creating new periodic structures. Moiré superlattices can induce mismatch of momentum space, resulting in new Brillouin zones, which in turn affect properties of Moiré superlattices. This review comprehensively discusses the emerging properties and features of Moiré materials, including important advancements in optics, electronics and thermal dynamics. We explored the synthesis methods of Moiré materials, structural modulation, and their impacts on properties and functionalities, and their potential applications in nanoscience and technology also been discussed. Furthermore, this paper introduced significant progress of Moiré materials in areas such as 2D materials, topological physics, and quantum effects, along with their potential applications in optoelectronic devices and other fields.
