(a) Scanning transmission electron microscopy image of a La05Sr05CoO3-δ film on SrTiO3(001). Note the in-plane structural modulation due to oxygen vacancy ordering (red arrows at top). Image adapted from [Gazquez et al., 2013]. (b) Scanning transmission electron microscopy image of a SrMnO3/LaMnO3 superlattice on SrTiO3. Note the structural asymmetry between the top and bottom interfaces of the LaMnO3 layers (red arrows on right). Image adapted from [May et al., 2008].
