Growth and characterization of PNZST thin films
نویسندگان
چکیده
We have grown and compared microstructures and dielectric properties of PNZST thin films prepared on two different substrates by sol /gel methods. To ensure a complete single-phase perovskite PNZST thin film, a capping layer of PbO must be added to the top surface of the thin film before final heat treatment. Microstructure characterization was examined with X-ray diffraction, scanning and transmission electron microscopy. Dielectric and antiferroelectric properties were investigated as a function of temperature. # 2002 Elsevier Science B.V. All rights reserved.

متن کاملNano-structural Characterization of Post-annealed ZnO Thin Films by X-ray Diffraction and Field Emission Scanning Electron Microscopy
ZnO thin films were deposited on Si(400) substrates by e-beam evaporation technique, and then post-annealed at different annealing temperatures (200-800°C). Dependence of the crystallographic structure, nano-strain, chemical composition and surface physical Morphology of these layers on annealing temperature were studied. The crystallographic structure of films was studied using X-Ray Diffracti...
