Ferroelectric films, which have a broad range of applications including the emerging energy technology, usually consist of nanoscale inhomogeneities. For polycrystalline films, the size and distribution of nano-grains determines the macroscopic properties, especially the field-induced polarization response. For epitaxial films, the energy of internal long-range electric and elastic fields during their growth are minimized by formation of self-assembled nano-domains. A ferroelectric film with a properly engineered polydomain nanostructure can have much better properties than those of a homogeneous single phase ferroelectric film or a polycrystalline one. Most of the time, the property enhancement (electromechanical, pyroelectric) comes from extrinsic contributions by collective field responses of the nanodomains. A well-desired exception is the improved energy storage density due to delayed saturation of the polarization in a polydomain ferroelectric film with reduced domain-wall mobility. Lastly, the nano-layers of interfaces between a ferroelectric film and its electrodes or between neighboring ferroelectric layers can be engineered to better gate the flow of electric charges, leading to reduced leakage currents and enhanced dielectric performance.
