Moire Synergy: An Emerging Playground by Coupled Moires

Moire superlattices of tunable wavelengths and the further developed coupled-moire ' systems, by artificially assembling two-dimensional (2D) van der Waals ( vdW) materials as designed, have brought up a versatile toolbox to explore fascinating condensed matter physics and their stimulating physicochemical functionalities. In this Perspective, we briefly review the recent progress in the emerging field of moire ' synergy, highlighting the synergetic effects arising in distinct multi-moire heterostructures of graphene and transition metal dichalcogenides (TMDCs). A spectrum of coupledmoire ' configurations, the advanced characterization, and the exploitation efforts on the moire-moire 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.
