摘要
The fatigue tests on lead zirconate titanate (PZT) multilayers were performed. The results so obtained were compared with single-layer n-type PZT films. The results indicate that fatigue is dominated by space-charge layers in each case, but that in the multilayer such space charge accumulates at the layer interfaces, rather than at the electrode-dielectric interface.
