By changing the electrode combination of Pt and LaNiO3(LNO), four capacitor types of Pt/PZT/Pt/Si, Pt/LNO/PZT/Pt/Si, Pt/LNO/PZT/LNO/Pt/Si, and Pt/PZT/LNO/Pt/Si, were prepared to investigate the fatigue and hysteresis characteristics of the solhyphen;gelhyphen;derived Pb(Zr0.53Ti0.47)O3(PZT) ferroelectric thin films. Among them, the (100)hyphen; and (001)hyphen;oriented PZT films were grown on the (100)hyphen;textured LNO electrode, but randomly oriented films were obtained on the Pt electrode. It was found that the use of LNO bottom electrode would improve the fatigue property quite significantly, but only the capacitor with LNO as both top and bottom electrodes is shown to be fatiguehyphen;free up to 1011cycles, and the shapes of the hysteresis loop almost unchanged after the fatigue test. copy;1996 American Institute of Physics.
