Abstract
The thickness-dependent energy gap oscillations in the metallic nanofilms are investigated by the use of the self-consistent numerical solutions of the Bogoliubov-de Gennes equations. We analyze, how the changes in the electron density (ne) and the electron-phonon coupling constant (g) influence the amplitude of the considered oscillations. It is found, that the increase in ne and the decrease in g can lead to a significant reduction of the oscillations amplitude. As a result, for the values of the mentioned parameters, which correspond to some of the realistic situations the thickness-dependent superconducting gap oscillations can be significantly suppressed. The computational results are compared with recent experimental data.
