Y_1铁电薄膜材料研究进展

Progress in Research on Y 1 Ferroelectric Thin Films

曾经引起铁电学界轰动的Ｙ１材料，其组成已公之于世，其结构为（Ｂｉ２Ｏ２）２＋（Ａｎ－１ＢｎＯ３ｎ＋１）２－氧化铋基层状铁电材料。目前研究较多的是ＳｒＢｉ２Ｔａ２Ｏ９，ＳｒＢｉ２Ｎｂ２Ｏ９以及它们的固溶体。文章介绍了有关Ｙ１材料的研究背景。

Y 1 material has caused a great sensation throughout the ferroelectrics field. Its composition and structure have been made known to the public. It is a bismuth oxide based layered material with the structure of (Bi 2O 2) 2+ (A n -1 B n O 3 n +1 ) 2- Now much attention is paid to SrBi 2Ta 2O 9, SrBi 2Nb 2O 9 and their solid solution.This paper introduces the research background of Y 1 series materials,and gives some reviews on the status and future development.
