The effects of processing variables, such as heat treatment conditions and number of deposited layers, on crystallinity and morphology of the final films were investigated. X-ray diffraction patterns show the oriented growth of the films. The rocking curves, obtained around the (006) LiNbO3 peak, revealed that the shape peak and the FWHM value were influenced by the processing variables. According to these parameters, some films presented very homogeneous dense and smooth surfaces, as shown by the SEM and AFM studies.1447-1451engElectron microscopyFilmsNiobates.Sol-gel processesX-ray methodsCoating techniquesCrystal orientationFilm growthHeat treatmentLithium niobateMorphologyMultilayersOrganic polymersScanning electron microscopySurfacesThin filmsX ray crystallographyPolymeric precursorX ray methodsFerroelectric materialsArtigo10.1016/S0955-2219(98)00469-5Acesso restrito2-s2.0-0032642679
