Abstract

Ultrahigh energy density dielectric film Dielectrics help hold charge as capacitors and are fundamental energy storage components. Improving energy density and other properties may help these materials be more competitive with batteries for energy storage applications. Pan et al. introduced a specific type of nanodomain structure in a BiFeO 3 -BaTiO 3 -SrTiO 3 solid solution that dramatically increased the energy density. The nanodomains were organized so as to minimize energy loss during polarization switching. The enhancement in the dielectric properties suggests that the strategy may be useful for designing high-performance dielectrics. Science , this issue p. 578
