Figure 8: Antisite defects on the surface.
From: Unravelling structural ambiguities in lithium- and manganese-rich transition metal oxides

(a) HAADF STEM image showing an apparently different structure in the thin areas (shown in the red-coloured rectangle). (b) A slightly tilted projection of spinel in [111] direction. The circled regions are the columns with mixed Li and TM atoms, which correspond to columns with antisite defects (TM in Li sites), giving higher intensity in HAADF images.
