Paper Abstract

Excellent electro-optic properties of SBN crystals explain the attempts to control the deposition of high ordered SBN thin films with the aim of optical waveguiding and processing integration. We have reported in this paper the first epitaxial growth of SBN on MgO substrates using a sputtering method. The SBN stoichiometry approach and single phase preparation have been shown to be possible on the basis of the deposition mechanisms analysis. In spite of the XRD unreliability as an experimental guide in the complex case of SBN growth, the occurrence of a strong orientation of the SN parasite phase on MgO is shown to provide an efficient XRD test of the stoichiometry approach. Epitaxial SBN thin films are obtained which exhibit two in-plane orientations mirror symmetric to the MgO cell axis.
