Recent Advances in Moiré Superlattice Structures of Twisted Bilayer and Multilayer Graphene
文献摘要：
Twisted bilayer graphene(TBG),which has drawn much attention in recent years,arises from van der Waals materials gathering each component together via van der Waals force.It is composed of two sheets of graphene rotated relatively to each other.Moiré potential,resulting from misorientation between layers,plays an essential role in determining the band structure of TBG,which directly relies on the twist angle.Once the twist angle approaches a certain critical value,flat bands will show up,indicating the suppression of kinetic energy,which significantly enhances the importance of Coulomb interaction between electrons.As a result,correlated states like correlated insulators emerge from TBG.Surprisingly,superconductivity in TBG is also reported in many experiments,which drags researchers into thinking about the underlying mechanism.Recently,the interest in the atomic reconstruction of TBG at small twist angles comes up and reinforces further understandings of properties of TBG.In addition,twisted multilayer graphene receives more and more attention,as they could likely outperform TBG although they are more difficult to handle experimentally.In this review,we mainly introduce theoretical and experimental progress on TBG.Besides the basic knowledge of TBG,we emphasize the essential role of atomic reconstruction in both experimental and theoretical investigations.The consideration of atomic reconstruction in small-twist situations can provide us with another aspect to have an insight into physical mechanism in TBG.In addition,we cover the recent hot topic,twisted multilayer graphene.While the bilayer situation can be relatively easy to resolve,multilayer situations can be really complicated,which could foster more unique and novel properties.Therefore,in the end of the review,we look forward to future development of twisted multilayer graphene.
