Paper Abstract

Ba0.7Sr0.3TiO3 thin film/Ba0.5Sr0.5TiO3 buffer layer/Pt/Ti/SiO2/Si(100) multilayer structures were investigated. The buffer layer was obtained from a highly dilute solution (0.1 M) by sol-gel technique through rapid thermal process. X-ray diffraction patterns show that the upper main BST film is preferential oriented and good in-plane relationship of BST(111)//Pt(111). After using the buffer layer, the leakage current was reduced two orders of magnitude. The dielectric properties are much better than those of the thin films without buffer layer at the same thickness of 150 nm.
