Ferroelectric materials are a special type of dielectric material in the form of thin films, widely applied in transducers, switches, sensors, capacitors, and memory devices due to their ease of modification and permanent properties. In this study, thin films of (0.4)BaTiO₃-(0.6)BaZr₀.₅Ti₀.₅O₃ (BT-BZT) were doped with pineapple peel extract and tantalum at concentrations of 0.5 wt%,…
