| 1 | Polarized Raman scattering study of PSN single crystals and epitaxial thin films显示文摘This paper describes a detailed analysis of the dependence of Raman scattering intensity on the polarization of the incident and inelastically scattered light in PbSc_(0.5)Nb_(0.5)O_(3)(PSN)single crystals and epitaxially compressed thin films grown on(100)-oriented MgO substrates.It is found that there are significant differences between the properties of the crystals and films,and that these differences can be attributed to the anticipated structural differences between these two forms of the same material.In particular,the scattering characteristics of the oxygen octahedra breathing mode near 810 cm^(-1) indicate a ferroelectric state for the crystals and a relaxor state for the films,which is consistent with the dielectric behaviors of these materials. | J.Pokorný I.Rafalovskyi I.Gregora F.Borodavka M.Savinov J.Drahokoupil M.Tyunina T.Kocourek M.Jelinek Y.Bing Z.-G.Ye J.Hlinka | 2015 | Journal of Advanced Dielectrics2015，5，2： | 0 |
