a ADF-STEM image of the WS2–WSe2 junction. Scale bar, 500 nm. b Dendrogram of the unsupervised learning workflow. c–e Real space maps from the unsupervised learning results showing different compositions and deformations in the sample. f–h 3D manifold structure displaying the data distribution in each round of the clustering. i Histogram of measured lattice constants of WS2 and WSe2 color-coded with results in the second-round clustering. j Histogram of measured rotation angles of WS2 color-coded with results in the third-round clustering of WS2.
