摘要: 利用推广的Ginzburg-Landau-Devonshire(GLD)理论,研究突变型和缓变型二级相变双层铁电薄膜界面对铁电薄膜性质的影响.

关键词: 铁电薄膜, GLD理论, 自由能, 铁电相变

Abstract: By means of the generalized Ginzburg-Landau-Devoshire (GLD) theory , the influence of the interface between two different materials with the second order transition on the properties of ferroelectric thin films with the step-type and slowly varying structures is studied.

Key words: ferroelectric thin film, GLD theory, free energy, ferroelectric phase transition
