Ferroelectric domain wall injection is depicted through a scanning electron microscopy image of a ferroelectric capacitor with four focusedion‐beam‐milled triangular holes. J. Marty Gregg and co‐workers show on page 293 that the holes induce electric field heterogeneity into the capacitor, represented by the colour gradient, to create localized field hotspots. Here, domain walls would be injected into the ferroelectric, illustrated by the cover image's central feature.
