| description | We reported a sandwich structured Pb(Zr<sub>0.4</sub>Ti<sub>0.6</sub>)O<sub>3</sub>/BaZr<sub>0.2</sub>T<sub>i0.8</sub>O<sub>3</sub>/Pb(Zr<sub>0.4</sub>Ti<sub>0.6</sub>)O<sub>3</sub> (PZT/BZT/PZT) film fabricated by using the sol−gel method, which was dense and uniform with a unique perovskite structure. The PZT/BZT/PZT films displayed high dielectric constants up to 1722.45 at the frequency of 10 kHz. Additionally, the enhanced energy storage density of 39.27 J·cm<sup>−3</sup> was achieved at room temperature and 2.00 MV/cm, which was higher than that of the individual BaZr<sub>0.2</sub>T<sub>i0.8</sub>O<sub>3</sub> film (21.28 J·cm<sup>−3</sup>). Furthermore, the energy storage density and efficiency of PZT/BZT/PZT film increased slightly with the increasing temperature from −140 °C to 200 °C. This work proves the feasibility and effectiveness of a sandwich structure in improving dielectric, leakage, and energy storage performances, providing a new paradigm for high-energy−density dielectrics applications. |
