Abstract

SBN60 films were prepared via the sol-gel route and the layer-by-layer growth technique. The films' structural quality and surface morphology were studied using X-ray diffractometry (XRD) and atomic force microscopy (AFM). Our results show that the use of crystalline and lattice matching substrates has marked effect on the films' orientation. Preferred and better-oriented (001) SBN layers have been obtained in thicker films. Enlarged and more uniformly distributed grain size and a much-reduced surface roughness have also been produced. Conditions for fabrication of dense and crack-free SBN60 films of up to 2.3 μm thick with good mean crystallinity are described.
