## Description

- description: Lattice strain effects on the piezoelectric properties of crystalline
    ferroelectrics have been extensively studied for decades; however, the strain
    dependence of the piezoelectric properties at nano-level has yet to be investigated.
    Herein, a new overview of the super-strain of nanoporous polycrystalline ferroelectrics
    is reported for the first time using a nanoengineered barium calcium zirconium
    titanate composition (Ba0.85Ca0.15)(Ti0.9Zr0.1)O3 (BCZT). Atomic-level investigations
    show that the controlled pore wall thickness contributes to highly strained lattice
    structures that also retain the crystal size at the optimal value (<30 nm), which
    is the primary contributor to high piezoelectricity. The strain field derived
    from geometric phase analysis at the atomic level and aberration-corrected high-resolution
    scanning transmission electron microscopy (STEM) yields of over 30% clearly show
    theoretical agreement with high piezoelectric properties. The uniqueness of this
    work is the simplicity of the synthesis; moreover the piezoresponse d33 becomes
    giant, at around 7500 pm V−1. This response is an order of magnitude greater than
    that of lead zirconate titanate (PZT), which is known to be the most successful
    ferroelectric over the past 50 years. This concept utilizing nanoporous BCZT will
    be highly useful for a promising high-density electrolyte-free dielectric capacitor
    and generator for energy harvesting in the future.
