- The interplay between the quantum size effect and superconductivity in the metallic Al nanofilms has been studied with the use of the self-consistent numerical solutions of the Bogoliubov-de Gennes equations. We have shown that the critical temperature of the metallic nanofilm oscillates as a function of the nanofilm thickness. This phenomenon results from the quasi-particle energy quantization induced by the confinement of electrons in the direction perpendicular to the film. For the ultrathin nanofilms with thickness 1-2 nm we have found that the critical temperature increases up to value several times higher as compared to the one measured in the bulk.
