Nanobeam 4D-STEM raw data of monolayer WS2-WSe2 lateral heterojunctions

The sample under investigation comprises a monolayer WS2-WSe2 lateral heterojunction featuring in-plane epitaxial interfaces. The datasets were acquired using an electron microscope pixel array detector (EMPAD) at Cornell University in 2016, with the following specifications: Magnification: 27.5 kx, Convergence angle: 1.2 mrad, C2 aperture size: 70, Spot size: 9. This dataset is from the same batch of datasets referenced in the paper by Han et al., Nano Letters 18, 3746-3751 (2018). Additionally, data from the same batch are also cited in the publication by Shi et al., npj Computational Materials 8, 114 (2022). Further details regarding the materials synthesis can be found in the paper by Xie et al., Science 359, 1131-1136 (2018).
