KINETICS OF LEAD OXIDE GRAIN BOUNDARY SEGREGATION IN LEAD ZIRCONATE TITANATE POLYCRYSTALLINE FILMS

A nonstationary model was proposed. The model describes macroscopic diffusion of intrinsic defects and their local interactions in lead zirconate titanate polycrystalline films during the annealing. The composition of PZT films was calculated in dependency on the temperature and the time of annealing. A possibility of the lead supersaturation was shown on crystalline surfaces of high textured PZT films.
