Enhancement of Dielectric Breakdown Strength and Recoverable Energy Density in Three‐Dimensional Heterointerfaces on BaTiO3–PbZrO3–PbTiO3 Films via Room‐Temperature Nano‐Clustering

Advanced Functional Materials, EarlyView.
A room‐temperature aerosol deposition process yields multiphase nano‐clustered dielectric capacitors containing discrete BaTiO3, PbZrO3, and PbTiO3 crystals. This architecture creates three‐dimensional heterointerfaces that induce interfacial charge trapping and effectively inhibit breakdown propagation.
