    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).
