Реферат:
Lanthanum oxide (La2O3)films were grown by the reactive dc magnetron sputtering and studied their structural, chemical and optical parameters. La2O3films were deposited onto Si substrates by sputtering La-metal in a reactive gas (Ar+O2) mixture at a substrate temperature of 200 °C. Reflection high-energy electron diffraction measurements confirm the amorphous state of La2O3films. Chemical analysis of the top-surface layers evaluated with x-ray photoelectron spectroscopy indicates the presence of a layer modified by hydroxylation due to interaction with atmosphere. Optical parameters of a-La2O3 were determined with spectroscopic ellipsometry (SE). There is no optical absorption over spectral range λ=250–1100 nm. Dispersion of refractive index of a-La2O3 was defined by fitting of SE parameters over λ=250–1100 nm
