dc.description.abstractStrontium bismuth titanate (SrBi4Ti4O15) thin films were deposited on (111) Pt/Ti/SiO2/Si Substrates by spin coating from the polymeric precursor method. Annealing in static air and dynamic oxygen atmosphere was performed at 700 degrees C for 2 h. The films were characterized by X-ray diffraction, atomic force microscopy and electric properties. The dielectric properties of SrBi4Ti4O15 films were found to be remarkably sensitive to the annealing atmosphere. The C-V characteristics of the metal-ferroelectric metal structure showed a typical butterfly loop that confirms the ferroelectric properties of the film related to the domains switching. SrBi4Ti4O15 thin films annealed in oxygen atmosphere showed lower ferroelectric behavior indicating a weak ferroelectricity along c-axis direction. Published by Elsevier Masson SAS.en
