Abstract
An oriented ferroelectric thin film element, which comprises a single-crystal substrate having thereon (a) a first epitaxial or oriented ferroelectric thin film prepared by a gas phase growth method and (b) a second epitaxial or oriented ferroelectric thin film prepared by application of a coating solution of an organic metal compound to the first ferroelectric thin film followed by heating the coated material. The oriented ferroelectric thin film element has a smooth surface and is useful as an optical guide element, light modulation element, etc. The second ferroelectric thin film can be formed by repeating the process of application of a coating solution of an organic metal compound followed by heating the coated material several times. The present invention also discloses a process for preparing the oriented ferroelectric thin film element.
