Figure 3. (A) Phase-field model of the epitaxial ferroelectric thin film with a substrate. The dashed box is a schematic of the model lattice under compressive misfit strain. (B) Phase-field model of the bent freestanding ferroelectric thin film. The dashed box is a schematic of the deformable model lattice under bending strain, and the purple line represents the neutral layer of the model. (C) The structural schematic of the phase-field method for freestanding ferroelectric thin films.
