DomAlN Structures and Poling Method of Barium Titanate Crystals
Source abstract
Abstract
The crystal BaTiO3 must be poled before its photorefractive applications. A technique forinspecting inclusions efficiently in the crystals has been established before poling crystals accordingto the 90° domAlN structures with the inclusions. With considering the character of the formationof 90° domAlN and 180° domAlN, the 90° domAlN can be removed by cooling crystal BaTiO3 slowlythrough the curie point (130.5℃), or by uniaxial pressing along a-axis. 180° domAlN can beremoved by applying electric field about 1~3×105V/m on the face (001).
