On Superconducting Transition Temperature in Amorphous Alloys of Simple Metals
Languages of publication
The Eliashberg equations are generalised to describe amorphous binary alloys. Equations for the electron-phonon coupling constant λ are obtained. An additional term caused by topological disorder appears in the expression for λ-constant. The features of amorphous state and their influence on λ-constant and superconducting transition temperature are emphasised and analysed. Theoretical results are illustrated by numerical calculations performed for some binary amorphous alloys of simple metals.
