Vertex-corrected tunneling inversion in superconductors: Pb
The McMillan-Rowell tunneling inversion program, which extracts the electron-phonon spectral function α2F (Ω) and the Coulomb pseudopotential μ from experimental tunneling data, is generalized to include the lowest-order vertex correction. We neglect the momentum dependence of the electronphonon matrix elements, which is equivalent to using a local approximation. The perturbation theory is perf...
متن کاملVertex-corrected tunneling inversion in electron-phonon mediated superconductors: Pb
The McMillan-Rowell tunneling inversion program, which extracts the electron-phonon spectral function aF(V) and the Coulomb pseudopotential m* from experimental tunneling data, is generalized to include the lowest-order vertex correction. We neglect the momentum dependence of the electron-phonon matrix elements, which is formally equivalent to using a local approximation. The perturbation theor...
متن کاملNonconstant electronic density of states tunneling inversion for A15 superconductors: Nb3Sn
We reexamine the tunneling data on A15 superconductors by performing a generalized McMillan-Rowell tunneling inversion that incorporates a nonconstant electronic density of states obtained from band-structure calculations. For Nb3Sn, we find that the fit to the experimental data can be slightly improved by taking into account the sharp structure in the density of states, but it is likely that s...
متن کاملResonant inversion of tunneling magnetoresistance.
Resonant tunneling via localized states in the barrier can invert magnetoresistance in magnetic tunnel junctions. Experiments performed on electrodeposited Ni/NiO/Co nanojunctions of area smaller than 0.01 microm(2) show that both positive and negative values of magnetoresistance are possible. Calculations based on Landauer-Büttiker theory explain this behavior in terms of disorder-driven stati...
متن کاملScanning tunneling spectroscopy of high-temperature superconductors
Tunneling spectroscopy has played a central role in the experimental verification of the microscopic theory of superconductivity in classical superconductors. Initial attempts to apply the same approach to high-temperature superconductors were hampered by various problems related to the complexity of these materials. The use of scanning tunneling microscopy and spectroscopy (STM and STS) on the...
