摘要

PMN-PT薄膜是一种弛豫型钙钛矿结构铁电材料,由于其具有较大的电光系数、纵向耦合系数、压电常数和介电常数,以及较低的介电损耗,而被应用于电容器、驱动器和非线性光学器件中。不同择优取向薄膜内部晶粒的排列方式不同,因此具有不同的性能。为研究不同择优取向PMN-PT薄膜,笔者从择优取向PMN-PT薄膜的生长、择优取向PMN-PT薄膜制备与性能等方面对PMN-PT薄膜的研究现状作详细介绍,相关结果将为择优取向PMN-PT薄膜的制备与性能提升提供参考。

Abstract

As a kind of relaxed perovskite structure ferroelectric material, PMN-PT films are widely used in capacitors, drivers and nonlinear optics due to its large electro-optic coefficient, longitudinal coupling coefficient, piezoelectric constant and dielectric constant and low dielectric loss. The inner grains of the films with different preferred orientations are arranged differently, so it have different properties. In order to research the different preferred orientated PMN-PT films, we made an investigation of PMN-PT films from the aspects of the growth, the preparation and properties of preferentially oriented PMN-PT films. In detail, the relevant results will provide a reference for the preparation and performance improvement of preferentially oriented PMN-PT films.

Key words: (1-x)PbMg1/3Nb2/3O3-xPbTiO3; preferred orientation; ferroelectric material; perovskite structure
