摘要：
Lead strontium titanate (Pb0.5Sr0.5)TiO3 (abbreviated as PST) thin films were deposited on Pt/Ti/SiO2/Si(100) substrates by using a sol-gel method with spin-coating processing. The crystalline films were studied by means of X-ray diffraction (XRD) and atom force microscopy (AFM). The results show that the film was annealed at 650°C for 30min with perovskite cubic phase, and the lattice parameter a=0.3919nm. The chemical states and chemical composition of the films were determined by X-ray photoelectron spectroscopy (XPS) near the surface. The results show that the extra lead oxides exist in film surfaces. The atomic ratio Pb:Sr:Ti:O in the near-surface region is 0.52:0.50:1.00:3.02, which is closer to the stoichiometry of (Pb0.5Sr b0.5)TiO3.
