Abstract

Epitaxial Pb(Zr, Ti)[O.sub.3] (PZT) thick films are grown on (100)SrRu[O.sub.3]/(100)SrTi[O.sub.3] and (100)SrRu[O.sub.3]/(100)LaNi[O.sub.3]/(100)Ca[F.sub.2] substrates by pulsed-metal organic chemical vapor symmetry. The studies have shown that the electrical properties of the polar-axis-oriented epitaxial thick films are similar to the predictions for PZT single crystals.

Abstract

Epitaxial (100)/(001)-oriented tetragonal Pb(Zr, Ti)[O.sub.3] films are grown on (100)SrT[O.sub.3] substrates by pulsed metal organic chemical vapor deposition and the films with Zr/(Zr+Ti) ratios have a strain-relaxed domain structure. The domain structure determined by the volume fraction of (001) orientation and the lattice parameters dependent on the Zr/(Zr+Ti) ratio are described by a geometrical model consistent with previous results for PbTi[O.sub.3] films.

Abstract

Epitaxial (100)/(001)-oriented PbTi[O.sub.3] films with thickness of 2.8 [micro]m are grown on Nb-dioped (100) SrTi[O.sub.3] substrates by pulsed metal organic chemical vapor deposition. The results have suggested that a-domains (a2/a3) and (a1/c1) domain configurations represent mostly strain-relaxed structures.
