Domain structures influence significantly the properties of ferroelectric materials. Here, the authors use phase-field simulations to show that spatially homogeneous defect charges in BiFeO3 may play a key role in the formation of the experimentally observed enigmatic zigzag domain structures, providing insights into pyramidal-domain formation in perovskite oxides.
