The sample is coherent WS₂-WSe₂ superlattice (Xie, et al. Science 359, 1131-1136 (2018)). The datasets were collected by electron microscope pixel array detector (EMPAD) under the condition described in this paper (Han, et al. Nano Letters, 18, 3746-3751 (2018)). The rotation angle between the real space and diffraction space in these datasets is 37 degrees. The data have also been analyzed in our recent paper (arXiv:2111.06496) and a conference proceeding (Shi, et al. Microsc. Microanal. 27 Suppl 1, 2021).
