Abstract

A new class of highly stable ferroelectric material, that is, a mesostructured SrTiO₃/BaTiO₃ composite film, obtained by a surfactant-templated sol-gel method is reported. Due to the concave surface geometry and abundant hetero-interface between SrTiO₃ (ST) and BaTiO₃ (BT) phases, a large number of strains can be created in the composite film, thereby leading to dramatic enhancement of ferroelectric property (see scheme).
