The Influence of the Growth Conditions on the Elastic Properties of SrLaAlO4 and SrLaGaO4 Crystals Studied by Brillouin Light Scattering

Abstract

Study of the optic and elastic properties of SrLaAlO4 and SrLaGaO4 crystals are presented. The investigated crystals were grown by Czochralski method. The elastic constants of SrLaAlO4 and SrLaGaO4 crystals at room temperature have been determined by Brillouin scattering method. Refractive indices have been measured independently by ellipsometry technique. The results are discussed in terms of the oxygen point defects, which can be created in the lattices of SrLaAlO4 and SrLaGaO4 crystals during the growth process.
