Abstract

A novel method for synthesis of Barium Strontium Titanate (BST) films with a high degree of texture is developed with a two-step hydrothermal reaction and without the need for costly equipment. The dielectric constant and ferroelectric properties of the film can be tuned by varying the Ba : Sr molar ratio of the materials. The maximum ambient temperature dielectric constant of these BST films can reach 811 when the Ba molar fraction (“x” in BaxSr1−xTiO3) is 0.71, which corresponds with the tetragonal to cubic phase transition of the solid solution. The ferroelectric behavior of the Ba0.91Sr0.09TiO3 film is confirmed by atomic force microscopy (AFM).
