本专利介绍一种铁电薄膜极化方法,其具体操作步骤是这样的,在薄膜的正反两侧(19)施加电极(10,11),以隔绝一小块的面积(22)。在施加可变电压的同时,将该块小面积压缩。 每个电极由一绝缘体(12,15)支承。绝缘体由一块坚硬的板(13,16)和一层介质膜(14,17)构成,其表面(14a,17a)与电极的 This patent describes a method for the polarization of ferroelectric thin films by the steps of applying electrodes (10, 11) on the front and back sides (19) of the film to insulate a small area (22). The small area of ​​the block is compressed while applying a variable voltage. Each electrode is supported by an insulator (12,15). The insulator consists of a rigid plate (13, 16) and a dielectric film (14, 17) whose surfaces (14a, 17a)
