이종층 PZT/PT 후막의 전기적 특성 = Electrical Properties of Heterolayered PZT/PT Thick Films

다국어 초록 (Multilingual Abstract)

The heterolayered PZT/PT thick films were fabricated by two different methods thick films of the PZT by screen printing method on alumina substrateselectrodes with Pt, thin films of PbTiO₃ by the spin-coating method on the PZT thick films and once more thick films of the PZT by the screen printing method on the BaTiO₃ layer. The structural and the dielectric properties were investigated for effect of various stacking sequence of sol-gel prepared PbTiO₃ coating solution at interface of the PZT thick films. The insertion of PbTiO₃ interlayer yielded the PZT thick films with homogeneous and dense grain structure with the number of PbTiO₃ layers. The leakage current density of the PZT/PbTiO₃-1 film is less that 4.41x10？？ A/㎠ at 5 V.
