Spatial coupling of ferroelectric domain walls and crystallographic defects in PbTiO 3 films is directly visualized via aberration‐corrected scanning transmission election microscopy (STEM) by Xiu‐Liang Ma and co‐workers in article 1600342. This is a schematic illustration based on atomic‐scale STEM mapping showing the atomic configurations of the formation of positively charged 90° domain wall as a result of spatial coupling between domain walls and dislocations.
