With the increasing demand for ceramic-based capacitors in energy storage and electronics, ferroelectrics have gained attention due to their high dielectric coefficient. However, near phase-transition temperature, a significant variation coefficient leads reduced temperature stability degradation of electrical properties, limiting applications. To address this, composite films with multiple temperatures can provide stable response over broad range. Conventional ceramic processing cannot achieve this interdiffusion during high-temperature sintering. overcome we utilized aerosol deposition (AD) process, which enables fabrication high-density at room while preserving distinct Curie (Tc) different compositions. We prepared three PZT compositions: Pb(Zr0.2Ti0.8)O3, Pb(Zr0.52Ti0.48)O3, Pb(Zr0.8Ti0.2)O3. Compared single-phase film exhibited higher across range overlapping phase transitions. The AD-fabricated offer enhanced thermal stability, making them suitable temperature-sensitive applications such as compact power electronics portable devices.
