This letter deals with the experimental observation of oscillations in the infrared reflectance from Nb ultra-thin films deposited on α-type SiO 2 substrates. P-polarized reflectance (Rp) measurements are made using a tunable p-polarized CO 2 waveguide laser using wavelengths between 9.2 and 10.4 μm. Several Nb/SiO 2 quantum wells were specially made by the RF sputtering technique. Tailored thicknesses run between 5.5 and 55 Å. Because of the strong influence from the chosen substrate, IR reflectivity was fitted to the optical response of our metal-substrate system by using the three-oscillator model and numerical calculations on the basis of the local field calculation for a single metallic quantum well. Although quantum size effects are well studied in semiconductor compounds, there are only a few studies of this effect in metallic films where the present investigation has its most important contribution.

Oscillations in the infrared reflectance from metallic ultrathin films are described as consequence of quantum size effects. In this contribution, we present experimental evidence of such oscillations for Nb ultrathin films deposited on α-type SiO 2 substrates. Also, it is shown how substrates influence the size effects and the amplitude but not the period of oscillations. Because of the strong influence from the chosen substrate due to absorption, IR reflectivity was fitted to the optical response of our metal-substrate and bare-substrate system by using the three-oscillator model and numerical calculations on the basis of the local field calculation for a single metallic quantum well. Although quantum size effects are well studied in semiconductor compounds, there are few studies of this effect in metallic films where the present investigation has its most important contribution. Measurements for p-polarized reflectance (Rp) are made using a tunable p-polarized CO 2 waveguide laser using wavelengths from the p-branch (9.4 to 9.7 μm) and R-branch (10.0 to 10.4 μm). Nb/SiO 2 ultrathin films were assembled by a conventional RF sputtering technique and tailored thicknesses were deposited from 5.5 to 55 Å.
