Superconducting energy gap and transition temperature of amorphous Pb55Bi45-films

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

Amorphous Pb55Bi45-films with thicknesses ranging between 8.9 nm and 38.1 nm are investigated with both dc and microwave transmission and reflection measurements. The observed influence of thermodynamic fluctuations on the dc resistance can be well described with the theory of Aslamazov and Larkin, and in the case of hf measurements with the conductivities derived by Bray and Rickayzen. BothT c and 2Δ(0) are found to decrease linearily with inverse film thickness leading toβ=2Δ(0)/kT c=5.4 independent of thickness. The result suggests a pair-weakening model to be the adequate description forT c- and 2Δ(0)-depression in amorphous Pb55Bi45-films.
