Abstract. The heterostructures La1-xSrxCoO3/Pb(Ta0.05 Zr0.48Ti0.47)O3(PTZT)/La1-x SrxCoO3 have been deposited on SiO2/Si(001) substrates using Pt/TiO2 as conductive barrier by pulsed-laser deposition. La0.25Sr0.75CoO3(25/75) bottom electrodes with a pseudo-cubic perovskite structure favors (001)-textured growth of PTZT films. The ferroelectric capacitor LSCO(25/75)/PTZT/LSCO(25/75) remains about 96% of its polarization after 5×1010 switching cycles at an applied voltage of 5 V and a frequency of 500 kHz. The cross-section morphology of scanning electron microscopy and Rutherford backscattering spectra show that no obvious interdiffusion occurs across the interfaces.
