Interface Modifications of Lead Zirconate Titanate Thin Films.

Electrical properties of ferroelectric thin films depend on the quality of not only the ferroelectric thin layer but also the ferroelectric/electrode interfaces. In the present study, attempts were made to minimize the Pb depletion at the bottom electrode/ferroelectric interface in lead zirconate titanate ferroelectric thin films by adding a PbO interfacial layer using a chemical solution deposition method. The crystallographic structure of the PZT thin films with and without PbO layer were examined by X-ray diffraction. The microstructure of the thin film samples was characterized using optical microscope and atomic force microscope. [ABSTRACT FROM AUTHOR]
