Résumé

It is well known that new effects appear in superconductors with the reduction of their size. Among them one is the most interesting – phenomenon of changing of critical temperature. It can be both decrease and increase in different metals, however, despite the number of existing works, there is still no generally accepted conception of what is exactly the origin of this effect. At the moment it is more or less clear, that this is a rather complicated mechanism, which is influenced by many factors, particularly connected with the sample’s manufacturing. Nevertheless, we suppose even after minimization of all impacts, the temperature of superconducting transition shifts anyway because of quantum size effect. We present here the results of the investigation of high-quality polycrystalline aluminum films and demonstrate the presence of quantumconfinement process that was not considered earlier.
