Abstract

La-doped BiFe_0.92Mn_0.08O₃ films with the composition from 0 to 20% (BLFMx) have been deposited on Si(100) substrates by a sol-gel route. X-ray diffraction analysis shows that the films are polycrystalline and exhibit the pure perovskite phase structure (R3c). The La dopant effects on the surface morphology, dielectric function, and optical transition of the films have been investigated by atomic force microscopy and spectroscopic ellipsometry at room temperature. The dielectric functions of the films have been uniquely extracted by fitting the measured ellipsometric spectra with a three phase layered model (air/film/Si) and the Tauc-Lorentz dielectric function model in the photon energy range of 0.5-3.5 eV. It is found that the optical transitions decrease with increasing La composition, which is crucial for future photoelectric device.
