Fig. 3: Phase-field simulations showing the relation between the electric field and the ___domain structure.
From: Reversible long-range ___domain wall motion in an improper ferroelectric
The influence of an electric field on the ferroelectric domains is displayed for a the initial configuration without an applied electric field and b at the maximum negative electric field. The continuous change of the simulated ferroelectric ___domain structure is displayed in a movie in the Supplementary Material (Supplementary Movie 2). c The polarization is extracted along the dotted line in panels a and b as a function of an equivalent triangular-shaped voltage sequence, analogous to our experiment (Fig. 1a). d Voltage-dependent data of the BE-PFM phase, obtained from experiment, extracted along a dotted line of the area of interest in Fig. 1d is displayed. The green dots represent a guide to the eye for the electric-field-dependent positions of the ___domain wall, determined through thresholding. Jump-like changes in the position are highlighted by white arrows.
