Abstract
The optical properties of the LaNiO3-x films were investigated using high-accuracy spectroscopic ellipsometry technique. The parameterized Drude and double Lorentzian oscillator dispersion relation was used to express the optical properties of the LaNiO3-x films. It was found that refractive index decreases with increasing oxygen partial pressure in the measured wavelength region except for the film with 50% oxygen partial pressure. The large stoichiometric ratio Ni:La was induced to the small resistivity of the LaNiO3-x films.
