摘要: Van der Waals heterostructures, as vertical stacks assembled by different 2D crystals, have been widely used to produce combinations with predetermined functionalities. Apart from the selection and the sequence of 2D crystals, current research efforts have primarily focused on tuning physical properties through controlling the twist angle, i.e., the moiré superlattice size. Here, we introduce an approach to property engineering by enhancing and controlling moiré-induced periodic strain in monolayer graphene, where the monolayer graphene is aligned with hexagonal boron nitride (hBN) on both sides to enable modulation of different stacking configurations at the three-layer interfaces. This structural phase transition leads to a rich variety of previously unreported electronic phase transitions. |
