Ferroelectric superlattice structures composed of three-dimensionally epitaxial PbTiO{sub 3} and PLT thin films have been successfully grown on SrTiO{sub 3} substrates by metalorganic chemical vapor deposition. The modulation structures were confirmed by {theta}-2{theta} XRD, and the excellent in-plane orientational relationship between the superlattice film and the substrate by (100), (110), and (111)-pole figures. The {phi}-scans through the (110) and (111) reflections were used as additional evidence for three-dimensional epitaxy. The substrate dependence of the epitaxial orientation of PLT and PbTiO{sub 3} single-layered thin films was investigated. PbTiO{sub 3} thin films with very high crystalline perfection can be successfully grown on KTaO{sub 3} substrates.
