Emergence of relaxor-like ferroelectric nature in nanograined Pb(Zr_0.95Ti_0.05)O₃ ceramic thick films for energy storage applications.

ABSTRACT: In this study, we demonstrated the nanostructuring of the ferroelectric (FE) phase of Pb(Zr_0.95Ti_0.05)O₃ (PZT-95/5) into a thick film with relaxor-like FE (RFE) characteristics. This transformation results in exceptionally high dielectric breakdown strength (E_DBS) and energy storage density properties. The high kinetic energy from aerosol deposition transformed the bulk PZT-95/5 from a normal FE system into a RFE system by forming a nanostructured grain with nanodomains within a nonpolar matrix. This nanostructure enables easy domain switching, resulting in low remanent polarization. The resulting high density of grain boundaries due to nanograin formation and the nonpolar structure act as barriers to charge flow, resulting in high breakdown stre
