ABSTRACT
In this letter, we report on the integration of epitaxial ferroelectric Pb(Zr, Ti)O[sub 3] (PZT) thin films on Si [100] substrates using a SrTiO[sub 3] (STO) template layer and a conducting perovskite (La[sub 0.5]Sr[sub 0.5])CoO[sub 3] electrode. X-ray diffraction studies reveal both in-plane and out-of-plane alignment of the heterostructure. The epitaxial films show extremely high remnant polarization as well as piezoelectric d[sub 33] coefficients compared to textured and untextured polycrystalline films.
