A review of experimental advances in twisted graphene moirè superlattice

Twisted moirè superlattice receives tremendous interests since the discovery of correlated insulating states and superconductivity in magic angle twist bilayer graphene (MA-TBG) Nature 556 80 (2018), Nature 556 43 (2018), even gives arise to a new field "twistronics" Science 361 690 (2018). It is a new platform hosting strong electron correlations, providing an alternative for understanding unconventional superconductivity. In this article, we provide a review of recent experimental advances in the twisted moirè superlattice, from MA-TBG to twisted double bilayer graphene and other two-dimensional materials based moirè superlattice, covering correlated insulating states, superconductivity, magnetism, et al.
