Boosting capacitive energy storage in relaxor ferroelectrics through polymorphic phase engineering.

ABSTRACT: Relaxor ferroelectric materials are promising for next-generation capacitors due to their high energy storage capacity. Polymorphic phase engineering, where different ferroelectric phases coexist, has been widely demonstrated as an effective approach to further boost capacitive energy storage performance of relaxor ferroelectrics, but the reasons for these improvements and how they compare to single-phase systems remain unclear. Here, taking dendrite-like PbZr_1-xTi_xO₃/MgO nanocomposites with defected as a model system, we systematically examine properties and capacitive energy storage performance for rhombohedral-dominant, rhombohedral/tetragonal-mixed, and tetragonal-dominant phases through phase-field simulations. We find that the rhombohedr
