ABSTRACT
An effective mechanism that generates large recoverable electric field induced strains in ferroelectric islands is studied by phase-field modeling. The large strains originate from the reversible 90° domain switching between a1 (a2) domains and c domains, driven by an applied electric field and an internal stress field. The electric field induced strains could be effectively controlled by the magnitude of island-substrate misfit and the aspect ratio of islands.
