1.Model Interface in Ceramic Multilayred FilmsThe nonlinear V-1 characteristics of semiconductive ceramics originate in a grain boundary or interface. The model interface in multilayred films such as Ni/ZnO (CoO)/Pr_6O_<11>/Au fabricated by the sputtering technique is used for understanding the nonlinear conduction mechanism. The study of such a model interface is useful for searching new artificial materials.Dielectric Anomaly in the Interface of CeramicsA broad peak above the Curie temperature of lead iron niobate pb (Fe_<1/2>Nb_<1/2>) O_3 may be related to interfaces at the grain boundary. Such dielectric anomaly and pyroelectric current of this compound may be explained by the space-charge polarization in the interfaces of the grain bounday due to ionic valence changes from Fe^<3+> to Fe^<2+> in B-site of the perovskite structure.

1.陶瓷多层膜中的模型界面陶瓷多层膜的非线性V-1特性起源于晶界或界面。用溅射法制备的多层膜如Ni/ZnO（CoO）/Pr_6O_ /Au中的模型界面<11>用于理解非线性导电机制。陶瓷界面的介电异常Pb（Fe_（1/2）Nb_（1/2））O_3在居里温度以上的一个宽峰可能与晶界界面有关。这种介电异常和热释电电流可以用钙钛矿结构B位Fe^&lt;3+&gt;到Fe^&lt;2+&gt;的离子价态变化引起的晶界界面的空间电荷极化来解释。
