Summary:Ferroelectrics are unique materials in which the spontaneous polarization can be reversibly switched by an external electric field. Among all the material groups, ferroelectric perovskite oxides exhibit the highest piezoelectric coefficients and can be integrated with other materials to design multifunctional composites. The intensive research of the physics underlying the electromechanical response has led to the development of materials with large piezoelectric properties [1, 2]. However, the large response achieved in single crystals and bulk ceramics has not been reproduced in ferroelectric thin films, where the piezoelectric response is obstructed by the mechanical clamping of the substrate.
