Moire superlattices, arising from the periodic Moire patterns formed by two-dimensional (2D) materials stacked with a slight lattice mismatch, have attracted significant attention due to their unique electronic and optical performances. This review provides an overview of recent advances in Moire superlattices, highlighting their formation mechanisms, structural characteristics, and emergent phenomena. First, we discuss the theoretical basis and experimental techniques employed in fabricating Moire superlattices. Then we outline various characterization methods that enable the investigation of the structural and electronic performance of Moire superlattices at the atomic scale. Afterward, we review the diverse range of emergent phenomena exhibited in Moire superlattices. These phenomena include the appearance of electronic band engineering, unconventional superconductivity, and topologically nontrivial state. We explore how these phenomena arise from the interplay between the original electronic properties of the constituent materials and the Moire pattern-induced modifications. Furthermore, we examine the potential applications of Moire superlattices in fields such as electronics, optoelectronics, and quantum technologies. Finally, we summarize the challenges and directions in Moire superlattice research, which include exploring more complex Moire patterns, understanding the role of twist angle and strain engineering, and developing theoretical frameworks to describe the behaviors of Moire systems. This review aims to provide a comprehensive understanding of the recent progress in Moire superlattices, shedding light on their formation, performance, and potential applications. The insights gained from this research are expected to pave the way for the design and development of next-generation functional Moire superlattices.
