摘要

只提供摘要形式。在KNbO/sub - 3/、LiNbO/sub - 3/、BaTiO/sub - 3/、SBN等铁电晶体中，基于光折变效应的混频性能受到材料多畴特性的强烈影响。为了获得高反射率，晶体体积内部和表面的单畴特征是非常理想的。本文介绍了一种铑掺杂BaTiO/ sub3 /晶体c面反平行铁电畴的检测和形状的结果。

Topography of the ferroelectric micro domains at the c-faces of a BaTiO/sub 3/:Rh crystal

Summary form only given. In ferroelectric crystals like KNbO/sub 3/, LiNbO/sub 3/, BaTiO/sub 3/, SBN the wave mixing performances based on the photorefractive effect are strongly affected by the polydomain feature of the material. To obtain high reflectivities, the monodomain feature is strongly desirable inside the volume of the crystal as well as at its faces. This work presents results on the detection and the shape of antiparallel ferroelectric domains at the c-faces of a rhodium doped BaTiO/sub 3/ crystal.
