A STUDY OF SUPERCONDUCTIVITY IN LEADBISMUTH ALLOYS USING ELCTRON TUNNELING TECHNIQUES,

Abstract

Some of the properties of superconducting leadbismuth alloy films were investigated using electron tunneling techniques. The superconducting energy gaps and transition temperatures as well as the effective tunneling density of electron states near the end point of the phonon spectrum were measured for various compositions of this alloy system. It was found that pure bismuth films as well as bismuth films containing small amounts of lead are not superconducting above 1 K. The results also indicate that for alloys with bismuth concentrations between about 35% and 75%, superconductivity is due partially to a proximity effect. (Author)
