Abstract
The dielectric response of a ferroelectric multilayer, having a design ed heterogeneity, has been studied near its phase transition range by use of the Landau-Ginzburg theory. The coherent lattice coupling betwe en ultrathin layers can be significantly strong, resulting in a broad phase transition of the superlattice system as a whole. The thickness of layers and their spatial distribution hold the keys for enhancing d ielectric properties in a broad temperature range.
