Nanoscale Ferroelectric Switchable Polarization and Leakage Current Behavior in (Ba0.50Sr0.50)(Ti0.80Sn0.20)O3 Thin Films Prepared Using Chemical Solution Deposition
Nanoscale switchable ferroelectric (Ba0.50Sr0.50)(Ti0.80Sn0.20)O3-BSTS polycrystalline thin films with a perovskite structure were prepared on Pt/TiO x /SiO 2 /Si substrate by chemical solution deposition. X-ray diffraction (XRD) spectra indicate that a cubic perovskite crystalline structure and Raman spectra revealed that a tetragonal perovskite crystalline structure is present in the thin fil...
متن کاملChemical solution growth of ferroelectric oxide thin films and nanostructures.
Chemical solution deposition (CSD) provides a low-cost, versatile approach for processing of thin and ultrathin ferroelectric films, as well as short and high aspect ratio ferroelectric nanostructures. This review discusses the state of the art in the processing of ferroelectric oxide thin films and nanostructures by CSD, with special emphasis on nucleation and growth phenomena. The effects of ...
متن کاملFerroelectric domain structures of epitaxial „001... BiFeO3 thin films
Ferroelectric domain structures of epitaxial BiFeO3 thin films on miscut 001 SrTiO3 substrates have been studied by transmission electron microscopy. BiFeO3 on 0.8° miscut substrates are composed of both 109° and 71° domains; in contrast, only 71° stripe domains are observed in BiFeO3 on 4° miscut 001 SrTiO3 substrates. The domain width in BiFeO3 on 4° miscut substrates increases as film thickn...
متن کاملInteraction between Ferroelectric Polarization and Defects in BiFeO3 Thin Films
Nanoscale impurity defects, with structures different from host materials, are known to commonly exist in functional complex oxides as a result of slight stoichiometry fluctuations that occur during material growth. Local perturbations induced by these defects, such as charge, strain, and atomic interaction, could have a profound effect on the physical properties of oxide nanomaterials. A direc...
متن کاملTunable Schottky Barrier in Photovoltaic BiFeO3 Based Ferroelectric Composite Thin Films
We examine the photo-assisted polarization loop in a BiFeO3 thin film under UV light illumination. BiFeO3 thin film prepared by pulsed laser deposition method onto the BaTiO3 thin film and the polarization behavior has been measured under poling voltage. Our results show the engineered polarization due to controllable schottky barrier under inverse poling voltage. This control on schottky barri...
