| 摘 要： | 以正丁醇钛和硝酸铋为原料，用Ｓｏｌ－Ｇｅｌ技术分别在Ｐｔ／Ｔｉ／Ｓｉ、Ｓｉ、Ｙ－ＺｒＯＴｉＯ３（１００）和石英玻璃基片上生长出ｃ轴取向的Ｂｉ４Ｔｉ３Ｏ１２薄膜，研究了衬底材料表面结构对Ｂｉ４Ｔｉ３Ｏ１２薄膜取得度的影响，晶格失配能和Ｂｉ４ＴｉＯ１２晶体的晶面能决定了薄膜的取向程度。

| Abstract: | The c - axis oriented Bi4Ti3O12 thin films were gained on Si, Y - ZrO2, SrTiO3 (100 ) single crystal substrates and Pt/Ti/Si, fused quartz substrates by sol - gel process with bismuth nitrate and titanium butoxide. It is discussed that the lattice structure of substrates affects the orientation degree of Bi4Ti3O12 thin films. The orientation degree of the films depends on the lattice siructure of substrates and the plane surface energy of Bi4Ti3O12. |
