Figure 3
ABF images viewed along a 
direction and O-O spacings.
(a) Upper panel is experimental annular bright-field image as viewed along [110]p direction. Lower panel show the inverted contrast and colored version of the image in the upper panel. (b) Upper panel shows a simulated annular bright-field image based on Model A proposed by Sheptyakov et al. as viewed along 
direction. Lower panel shows the inverted contrast and colored version of the image in the upper panel. (c) O-O spacing as viewed in the [110]p projection of the fully oxygenated Co-O layer. d) O-O spacing as viewed in the 
projection of the fully oxygenated Co-O layer.
