Ferroelectric domain wall injection has been demonstrated by engineering of the local electric field, using focused ion beam milled defects in thin single crystal lamellae of KTiOPO4 (KTP). The electric field distribution (top) displays localized field hot‐spots, which correlate with nucleation events (bottom). Designed local field variations can also dictate subsequent domain wall mobility, demonstrating...
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...
