a, STEM image of a 0° heterobilayer. The moiré superlattice is marked by white solid lines showing a periodicity of ~ 7.6 nm. b, Schematic of the moiré pattern of the WS2-WSe2 heterobilayers and their supercells (black) for a twist angle of 0°, respectively. Brown, yellow, and orange circles mark regions with high-symmetry stacking configurations. c, Large-scale STEM image for a 60° heterobilayer.
