Size, shape, and orientation dependence of the field-induced behavior in ferroelectric nanoparticles
Original language description
Ferroelectric (FE) composite materials are attractive for a range of applications in future functional devices. Here, we utilized a free energy based computational approach to investigate the electric-field driven response of isolated FE nanoparticles embedded in a dielectric matrix and its dependence on particle size, shape, and orientation of the applied field. Particle shapes belonging to the superellipsoidal family were considered, including octahedral, spherical, and cuboidal structures, as well as a number of intermediate geometries. In perovskite nanoparticles of all shapes that are large enough to support a domain wall (DW) at zero applied field, we observed polar switching by a formation of intermediate phases, which possess an appreciable amount of vorticity stemming from the DW motion through the FE inclusion volume. The system coercive field and energy storage efficiency were found to be strongly dependent on the particle shape and the orientation, but not on its size.
