Barium Titanate (BaTiO3) is a ferroelectric material which has a high dielectric constant. Barium Titanate can be doped with Zr which forms a thin BaZr0.5Ti0.5O3 layer. The thin layer of Barium Zirconium Titanate (BZT) has been successfully fabricated on an FTO substrate using sol-gel method and growing with spin coating. The thin films were annealed at 700oC for 30, 60, 90 and 120 minutes.…
