Ferroelectric materials have conventionally used in memory storage devices, nanogenerators, sensors, microelectromechanical devices (MEMS), energy harvesting, and actuators [7]. Today, these materials have also demonstrated potential in the solution to environmental-related problems, such as water cleaning using multicatalysis processes.
However, for ferroelectric energy storage capacitors, a small remanent polarization (P r) is also necessary for obtaining higher discharged energy storage density (W d) and efficiency (η). The classical ferroelectric materials have smaller W d and η values due to their higher P r, which limits their commercialization [[4], [5], [6]].
