Influence of Ni-dopant on structural and optical properties of Ba0.6Sr0.4TiO3thin film by sol-gel technique

摘要：

The pure and Ni-doped Ba0.6Sr0.4TiO, thin films were prepared on Si and LaNiO/Si substrates via sol-gel technique, respectively. The microstructure and surface morphology of the films were characterized using x-ray diffraction and atomic force microscope. The films on LaNiO3/Si substrate were wellcrystallized of the perovskite structure, and the diffraction peaks corresponded to BST standard pattern quite well. The Raman spectra showed the Ni dopant could improve the crystal quality of the BST films on Si substrate. The optical properties of the pure and Ni-doped films were studied by spectroscopic ellipsometry at room temperature.
