| Title: | Optical and electro-optic anisotropy of epitaxial Ba₀.₇7Sr₀.₃TiO₃ thin films | Authors: | Wang, DY Li, S Chan, HLW Choy, CL |
Issue Date: | 8-Feb-2010 | Source: | Applied physics letters, 8 Feb. 2010, v. 96, no. 6, 061905, p. 1-3 | Abstract: | The anisotropic optical and electro-optic properties of ferroelectric Ba₀.₇Sr₀.₃TiO₃ thin films, deposited on highly transparent single-crystal MgO (001),(011), and (111) substrates using pulsed laser deposition, were investigated. The experimental results show a strong correlation between optical, electro-optic properties, and the orientation of Ba₀.₇Sr₀.₃TiO₃thin films. The linear electro-optic coefficient rc of the (001), (011) , and (111) -oriented Ba₀.₇Sr₀.₃TiO₃ thin films are 99.1, 15.7, and 87.8 pm/V, respectively. Such a correlation may be attributed to the orientation dependent distribution and magnitude of spontaneous polarizati. | Keywords: | Barium compounds Crystal orientation Dielectric polarisation Electro-optical effects Energy gap Epitaxial layers Ferroelectric materials Ferroelectric thin films Refractive index Strontium compounds Transparency |
