High-quality aluminum films on GaAs substrates were experimentally studied. A noticeable increase in the critical temperature of the superconducting transition with a decrease in the film thickness was found. The effect is interpreted as manifestation of the quantum size effect, which affects both the density of electron states and the electron-phonon interaction.
