'systematically coordinates atomic-level lattice distortions, nanoscale domain engineering, microstructural grain boundary control... Under low electric fields: breaks long-range ferroelectric ordering into dynamic polar nanodomains maximizing polarization differences/ energy efficiency... moderate/ high electric fields: chemical doping, high-entropy strategies, multi-phase heterostructures suppress polarization saturation/ elevate dielectric breakdown strength... lead-free, miniaturized, high-power pulse dielectric capacitors"
