Barium strontium titanate (Ba 0.9 Sr 0.1 TiO 3 ) ferroelectric thin films have been grown on Pt/Ti/SiO 2 /Si substrates by a modified chemical solution route. X-ray diffraction and Raman spectroscopy measurements show that the films have an excellent crystallinity and crystallize in a tetragonal structure. Field-emission scanning electron microscopy and atomic force microscopy investigations show that the films have a columnar structure with large grains of 80-200 nm in diameter. For an electric field of 320 kV/cm, the remnant polarization and the coercive field are 7.8 μC/cm 2 and 56 kV/cm, respectively. The optical constants (n, k) of the Ba 0.9 Sr 0.1 TiO 3 thin films are obtained by spectroscopic ellipsometry in the spectral range between 0.3 and 1.7 μm, and the band-gap energy is determined to be approximately 3.6 eV.
