- Аннотация: Nd-modified PZT @PNZT,Pb0.97Nd0.02(Zr0.55Ti0.45)O3# thin films were deposited using a pulsed XeCl-excimer laser on single-crystal MgO~100! substrate at room temperature. After deposition, the PNZT thin-film samples were post-annealed at three different temperatures of 700, 800, and 900 °C. The crystal structure and crystallite size distribution were measured using conventional x-ray diffraction methods. Atomic force microscopy was used for the surface morphology characterization of both amorphous and polycrystalline films. Detailed grain structure of annealed PNZT films was studied in perpendicular film-substrate cross sections using field-emission scanning electron microscopy ~FESEM!. When annealing temperature increased from 700 to 900 °C, an orientation of growing grains in the film with ~001! planes parallel to the film surface took place. The mean crystallite size increased from 210 to 330 Å, respectively. FESEM micrographs revealed a subpopulation of columnar grains in the films growing downward from the upper surface of the film as a result of secondary grain growth due to minimization of the surface, strain, and ferroelectric depolarization energies. At the same time, the surface roughness was considerably decreased.
