Abstract We study a silicon-based PbTiO3/Pb(Zr0.53Ti0.47)O3/PbTiO3 capacitor, prepared by an improved sol-gel method. The ferroelectric capacitor, with high remanent polarization of 15μC/cm2 at a coercive field of about 30kV/cm, an ultra-low leakage current density of 0.1nA/cm2, and almost fatigue free properties, It can be used as a promising candidate for ferroelectric memory devices.
