摘要：

The electro-optic effect of ZnO epitaxial films was studied. Since the electro-optic effect in ZnO is inferior to that of ferroelectric materials, an increase in the electro-optic effect was expected in ZnO having ferroelectricity, due to the increase in the dielectric constant. Although Li and Mg doped ZnO film exhibited electro-optic response, the mobile Li ions influenced the polarization behaviour. To eliminate the electro-optic effect induced by other space charge effects, the birefringence shift measurement was performed. The measurement with ac electric field at various frequencies could abstract the electro-optic effect of Mn-doped ZnO thin films induced only by dipolar polarizability. (C) 2003 Elsevier B.V.
