摘要：

Modified lead titanate thin films with a nominal composition of Pb0.88La0.08TiO3 (PTL) have been prepared by chemical solution deposition (CSD) onto annealed Ti/Pt/Ti/(100)Si and Pt/TiO2/(100)Si. Composition and heterostructure of the PTL films on the two substrates have been studied by Rutherford backscattering spectroscopy (RBS). Composition of the PTL films on the two substrates is similar and close to the nominal one. However, the Ti/Pt/Ti/(100)Si and Pt/TiO2/(100)Si substrates induces different textures in the PTL films. The films on Ti/Pt/Ti/(100)Si developed a (111) preferred orientation, whereas the films on Pt/TiO2/(100)Si have a (100) (001) mixed preferred orientation. (C) 2001 Elsevier Science Ltd.
