| Abstract: | Thin Tl/Te-films are condensed onto a cooled substrate at 4 K. An amorphous phase is obtained. The maximum superconducting transition temperature of the amorphous Tl/Te-films is 4.2 K. Measurements of the energy gap by superconducting tunneling yield a ratio 2Δ/k T c =4.6 for amorphous Tl/Te-films and 2Δ/k T c =3.8 for disordered, pure Tl-films. |
