Abstract
Germanium-noble metal alloys are superconducting after quench-condensation. The same transition temperatures of about 3.5 K are obtained by implantation of Cu into Ge films. Irradiation experiments with Krypton show that lattice disorder is essential for the occurrence of superconductivity. The results harmonize with the concept of a homogeneous, liquid-like amorphous phase in which superconductivity is ascribed to metallic Ge.
