Abstract

Oxygen-plasma treatment has been done on Bi_3.25La _0.85Ti₃O₁₂ (BLT) films for lower crystallization temperatures and improved ferroelectric properties. The films, prepared by metal organic decomposition method on Pt and IrO₂ electrodes sputtered on Al₂O₃/SiO₂/Si substrates, were pre-annealed at the relatively low temperatures of 550 and 600 °C, followed by room temperature microwave oxygen-plasma treatment. The oxygen-plasma-treated BLT films showed very good ferroelectric characteristics after a final furnace annealing at 600 °C.
