## Description

- description: Lattice reconstruction and corresponding strain accumulation play a
    key role in determining the electronic band structure of two-dimensional moir
    ́e super- lattices, including those of transition metal dichalcogenides (TMDs).
    Imaging experiments of TMD moir ́e systems have so far provided a qualitative
    under- standing of the end product of this lattice relaxation process in terms
    of in- terlayer stacking energy, while quantitative models have relied exclusively
    on theoretical simulations. Here, we use interferometric four-dimensional scanning
    transmission electron microscopy to quantitatively map the mechanical defor- mations
    through which reconstruction occurs in small-angle twisted bilayer MoS2 and WSe2/MoS2
    heterobilayers with sub-nanometer resolution. We find that lo- cal rotations govern
    the intrinsic reconstruction process for both parallel- and anti-parallel orientations
    of twisted homobilayers, while local dilations dominate in heterobilayers with
    a sufficiently large lattice constant mismatch. Extrinsic uniaxial heterostrain,
    which introduces a lattice constant difference in twisted homobilayers, leads
    to further accumulation as well as redistribution of recon- struction strain,
    offering another route to modify the moir ́e potential landscape.
