The moiré superlattice is a type of artificial crystal structure that is created by stacking two layers of materials with a small relative twist angle. The term “moiré” refers to the interference pattern that is created between the two layers when they are stacked in this way, which can give rise to new electronic properties that are not present in either of the individual layers. In twisted bilayer graphene, some of the interesting properties that have been observed in moiré superlattices include the emergence of new electronic bands, the formation of unconventional superconductivity, and the nature of correlated insulating behaviours.

The moiré superlattice is a type of artificial crystal structure that is created by stacking two layers of materials with a small relative twist angle. The term “moiré” refers to the interference pattern that is created between the two layers when they are stacked in this way, which can give rise to new electronic properties that are not present in either of the individual layers. In twisted bilayer graphene, some of the interesting properties that have been observed in moiré superlattices include the emergence of new electronic bands, the formation of unconventional superconductivity, and the nature of correlated insulating behaviours. Apart from twisted bilayer graphene, twisted bilayer transition metal dichalcogenides (TMDs) are a fascinating class of moirématerials that have garnered a lot of attention in recent years due to their unique electronic properties. In these materials, two layers of TMDs are stacked on top of each other with a small twist angle. One of the most exciting properties of twisted bilayer TMDs is their ability to exhibit correlated electron behavior and signatures of superconductivity at low carrier density.
