Ferroelectric materials are thin-film dielectric substances widely used in electronic devices such as sensors, capacitors, and memory due to their ease of modification and permanent properties. This study aims to synthesize and analyze thin films of (0.3)BaTiO₃-(0.7)BaZr₀.₅Ti₀.₅O₃ (BT-BZT) doped with pineapple peel extract and tantalum at concentrations of 0.5 wt%, 1.0 wt%, and 1.5 …
