a Projection of the reciprocal space obtained from PEDT data following the indexing of the first crystal (green). The second visible lattice (blue) corresponds to a second adjacent crystal and was measured in the same data set. b The structure of oA-La2O2S1.5 solved and refined from PEDT data set. The right side of the panel represents the simulated HAADF-STEM image along [010] on the basis of the oA-La2O2S1.5 structure model. c The experimental HAADF-STEM image acquired in a well-organized domain oA-La2O2S1.5 superimposed with the simulated one.
