説明:

We demonstrate unprecedented control over the interactions by locally modifying the interlayer separation between graphene and hBN, which we achieve by applying pressure with a scanning tunneling microscopy (STM) tip. For the case of nearly aligned graphene on hBN, the graphene lattice can stretch and compress locally to compensate for the slight lattice mismatch between the two materials. We find that modifying the interlayer separation directly tunes the lattice strain and induces commensurate stacking. Our results open a path towards tailored electronic properties of vdW heterostructures controlled through the interlayer separation degree of freedom.
