SUPERCONDUCTIVITY AND PHONON SPECTRA OF DISORDERED THIN FILMS.

摘要: Abstract Disordered and recrystallized superconducting thin films of Pb, Sn Bi are investigated by tunneling measurements. The coupling parameter times phonon density states α ( ω ) 2 F ), the weighted moments 〈ω〉 〈ω 〉, constant λ Coulomb pseudo-potential μ ∗ determined from conductances. disorderd always show strongly increased slopes at small energies significant enhancements λ. calculated shifts T c in agreement with experiments.
