On a observé une double transition supraconductrice dans des films minces Al-Ge obtenus par coévaporation. Cette double transition est observée dans la transition résistive en fonction de la température et dans la caractéristique courant-tension. Une interprétation des résultats est proposée en termes de la théorie de percolation.A double superconducting transition in co-evaporated Al-Ge films can be observed in both their resistance-temperature and current-voltage characteristics. An explanation is offered in terms of percolation theory
