    Current-induced relaxation of charge imbalance in superconducting phase-slip centers (1982)
    Springer
    Journal of low temperature physics 46 (1982), S. 555-563 
    Details
    ISSN: 1573-7357

    Topics: Physics
    Notes: Abstract In superconductors with a relatively long inelastic scattering time, relaxation of charge imbalance generated in phase-slip centers will be dominated by elastic scattering in the presence of a supercurrent. The spatial dependence of the electrochemical potential is calculated. Important qualitative differences occur from the usual model of phase-slip centers, based on relaxation by inelastic scattering.

    Phase-slip centers in superconducting aluminum strips (1983)
    Springer
    Journal of low temperature physics 53 (1983), S. 633-671 
    Details

    Notes: Abstract Phase-slip centers in aluminum strips are analyzed in detail. Measurements have been performed on the spatial dependence of the electrochemical potential and the energy gap. Exponential decay of the quasiparticle potential is found, with a diffusion length that follows a (T c −T)−0.25temperature dependence. The relaxation rate is higher than expected, corresponding to an inelastic scattering time of 4 ns. This is likely due to enhanced electron-electron scattering in two-dimensional metals. Gap measurements show depression of the gap in a region of more than 20 µm. Longitudinal nonequilibrium of the quasiparticles is probably responsible. For the time-averaged supercurrent divided by the critical current a value of 0.3 is found in the neighborhood ofT c ,lower than observed in tin and indium.

    Self-heating of phase-slip centers (1983)
    Springer
    Journal of low temperature physics 53 (1983), S. 673-683 
    Details
    ISSN: 1573-7357
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A model is constructed to describe the current-voltage characteristics of phase-slip centers, taking into account the heat generated by the nonequilibrium quasiparticle current and the oscillating supercurrent. If the temperature rise is sufficient to reachT c ,the description can be continued with the model of a normal hot spot between superconducting regions. Additional Joule heat is generated inside the superconductor due to the charge imbalance at the normal-superconducting boundaries. Analytical results in the limit of small heating are presented. A numerical solution generates current-voltage characteristics observed experimentally. The results obtained with the model differ in a qualitative and in a quantitative way from those found previously by Skocpol, Beasley, and Tinkham. A comparison with experimental results on tin and aluminum microstrips is made.

    Microwave-enhanced critical current in superconducting aluminum strips (1984)
    Springer
    Journal of low temperature physics 54 (1984), S. 607-618 
    Details
    ISSN: 1573-7357
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A study has been made of the enhancement of the critical current in superconducting aluminum microstrips by microwave radiation. The observed enhancement is compared to calculations based on the Eliashberg theory modified for application to critical current enhancement. Theory and experiment are in reasonable agreement if the strongly temperature-dependent microwave impedance is taken into account.
