Moiré Synergy: An Emerging Game Changer by Moiré of Moiré

Abstract

Moiré superlattices of tunable wavelengths and the further developed moiré of moiré systems, by artificially assembling two-dimensional (2D) van der Waals (vdW) materials as designed, have brought up a versatile toolbox to explore fascinating condensed mater physics and their stimulating physicochemical functionalities. In this Perspective, we briefly review the recent progress in the emerging field of moiré synergy, highlighting the synergetic effects arising in distinct dual moiré heterostructures of graphene and transition metal dichalcogenides (TMDCs). A spectrum of moiré of moiré configurations, the advanced characterization and the exploitation efforts on the moiré-moiré interactions will be discussed. Finally, we look out for urgent challenges to be conquered in the community and some potential research directions in the near future.
