Moire Patterns In 2d Materials: A Review

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 moire superlattices, such as unconventional superconductivity, photonic dispersion engineering, and ferromagnetism. In this review, we summarize the methods to prepare moire superlattices in the van der Waals materials and focus on the current discoveries of moire pattern-modified electrical properties, recent findings of atomic reconstruction, as well as some possible future directions in this field.
