Superconductivity was observed for the first time for Ge1−xAux films prepared by rf sputtering at room temperature. The films are composed of the diamond structure (Ge)-and hexagonal close packing (Ge–Au)-crystalline phases. The origin of superconductivity is discussed in the light of recent observations of superconductivity for multi-layered films and very thin-Ag films on Ge clean surfaces.
