  • METHOD FOR THE PREPARATION AT LOW TEMPERATURES OF FERROELECTRIC THIN FILMS, THE FERROELECTRIC THIN FILMS THUS OBTAINED AND THEIR APPLICATIONS
    Publication number: 20130015391
    Abstract: A processing technology is for the fabrication at low temperatures of ferroelectric crystalline oxide thin films, among others PbZrxTi1-xO3 (PZT) (<400° C. for PZT) with ferroelectric properties appropriate for integration in devices. The method is also for the fabrication of ferroelectric thin films of bronze tungsten (A2B2O6), perovskite (ABO3), pyrochlore (A2B2O7) and bismuth-layer (Bi4Ti3O12) structures, in which A and B are mono, bi-, tri-, tetra- and pentavalent ions.
