摘要
The electrical properties of PZT thin films grown by MOCVD on Pt, Ir, IrO2 and Ir/IrO2 bottom electrodes, and the effects of various top electrode materials on the electrical properties of these PZT films, were investigated. Regardless of the top electrode materials, PZT films prepared on Ir, IrO2 and Ir/IrO2 showed a smaller dielectric constant and Pr, and showed larger Pc than those of PZT films on both Pt top and bottom electrode. Ir/IrO2/PZT/IrO2/Ir/SiO2/Si capacitors showed no fatigue up to a switching cycle of 10(11) and showed a leakage current density of 10(-7) A/cm(2) at 3V.
