我们报告，铁电反型层可以形成在LiTaO 3的质子交换在苯甲酸熔体，然后在低于居里点的温度下热处理。结果表明，反型层出现在-c表面的LiTaO 3，而它出现在+c表面的LiNbO 3。还报道了质子交换和热处理条件对反型层厚度的依赖性。
We report that a ferroelectric inversion layer can be formed in LiTaO3 by proton exchange in benzoic acid melts followed by heat treatment at temperatures just below the Curie point. It is demonstrated that the inversion layer appears at the −c surface for LiTaO3, whereas it appears at the +c surface for LiNbO3. The dependence of the inversion layer thickness on the conditions of proton exchange and heat treatment is also reported.
