Abstract
Structure changes and dielectric properties of strained artificial superlattices of BaTiO3/SrTiO3 are discussed in this article. A large strain of 0.5-1GPa is introduced at the interface between BaTiO3 and SrTiO3 layers, and a large dielectric constant of 900 is observed with stacking periodicity of 2 unit cells/2 unit cells for the total thickness of 2000Å. The superlattices show drastically different dielectric behavior from that of the solid solution (Sr, Ba) TiO3 films. Broad maxima of the dielectric constants occur around 40-50°C and the values remain large even at a temperature above 200°C.
