Studies on the structure and microstructure of lead strontium titanate thin films
摘要
Pb1-xSrxTiO3 (0≤x≤0.9) thin films on Si (100) substrate were prepared by the sol-gel process and their characteristics were investigated as a function of strontium content(x). With increasing of the strontium content, the tetragonality (c/a) was slightly decreased, the splitting peaks become less prominent and the splitting peaks tend to merge into a single peak. Furthermore, the grain size of the films was systematically reduced with the increase in strontium content.
