Notes

Films GdF₃; Deposited by thermal evaporation on c-Si; Five samples with a polycrystalline structure and nominal thicknesses 20–600 nm; Multi-sample method; Heterogenous data processing combining ellipsometric and spectrophotometric measurements; Inhomogeneous layers; Optical constants correspond to the thinest film; Room temperature.
