Abstract

Lead-free piezoelectric thin films of composition (1-x)Bi_0.5Na_0.5TiO₃-xBi_0.5K_0.5TiO₃-0.03SrZrO₃ (x = 15, 17.5, 20 and 22.5%) have been created using the sol-gel spin coating approach over a Pt/Ti/SiO₂/Si substrate. The X-ray diffraction profiles suggest that a remarkable transition from tetragonal to rhombohedral-phase passing by a morphotropic phase boundary (MPB) occurs at x values from 17.5 to 22.5%. Additionally, the surface morphology, piezoelectric response, ferroelectric behavior, and energy storage properties were also investigated. Piezoresponse force microscopy (PFM) depicted a strong piezoelectric and ferroelectric behavior at a very localized size; at x = 17.5%. The piezoelectric behavior was enhanced and reached values of the recoverable energy storage density (J_rec) and the energy storage efficiency (η) of 3.27 J/cm^3, and 39.9%, respectively. Such materials are anticipated to play an important role in lead-free devices.
