Abstract
The R(T) dependences of thin superconducting aluminum films deposited on leucosapphire and gallium arsenide substrates by electron beam sputtering and molecular beam epitaxy have been experimen-tally studied. Regardless of morphology, a noticeable increase in the critical temperature of the supercon-ducting transition with a decrease in the film thickness is found. The effect is interpreted as a manifestation of the quantum size effect.
