Optical properties of metallic films
WebWhen the measurement involves two or more films in a stack of films, the theoretical expression for reflectance must be expanded to include the n (λ) and k (λ) spectra, plus thickness, t, of each film. However, the regression may not converge to unique values of the parameters, due to the non-linear nature of the expression for reflectance. WebJan 1, 2014 · Most metallic thin films are polycrystalline, consisting of a large number of grains which individually are normally considered as single crystals.
