Effect of Annealing Temperature on Epitaxy and Surface morphology of $Pb(Zr, Ti)O_3$ Thin Films on MgO (100) Substrate by Dipping-Pyrolysis Process
ABSTRACT
$Pb(Zr,Ti)O_3$ (Zr : Ti=0.52:0.48) thin films were fabricated bydipping-pyrolysis process on MgO(100) sub-strates with metal naphthenates used as staring materials. Effects of final heat-treatment temperatuer on epitaxy and surface morphology of the films were investigated. Highly oriented (00l)/(h00) films prefired at $200^{circ}C$ were obtained at final heat-treatment temperatures of $750~800^{circ}C$ and from the results of the X-ray diffraction pole-figure analysis these films had epitaxial relationship with substrates used. Film heat-trated at $750^{circ}C$ had a smooth surface and showed no distinct texture while the rosette-type microstructure caused by lead volatilization was observed in the film after heat -treatment at $800^{circ}C$
Key words: $Pb(Zr, Ti)O_3$ thin films, Dipping-pyrolysis process, MgO(100), Metal naphthenates, Epitaxial relationship
