Fluctuation Spectroscopy in Granular Superconductors with Application to Boron-doped Nanocrystalline Diamond
David T. S. Perkins, Georgina M. Klemencic, Jonathan M. Fellows +1
We perform a detailed calculation of the various contributions to the fluctuation conductivity of a granular metal close to its superconducting transition. We find three distinct r…
Absence of singular superconducting fluctuation corrections to thermal conductivity
Douglas R Niven, Robert A Smith
We evaluate the superconducting fluctuation corrections to thermal conductivity in the normal state which diverge as T approaches T_c. We find zero total contribution for one, two…
Width and Magnetic Field Dependence of Transition Temperature in Ultranarrow Superconducting Wires
Robert A Smith, Beccy S Handy, Vinay Ambegaokar
We calculate the transition temperature in ultranarrow superconducting wires as a function of wire width, resistance and applied magnetic field. We compare the results of first-ord…
A Consistent Treatment of Strong Coupling in Disordered Superconducting Films
Margit Steiner, Robert A Smith
We develop a consistent treatment of disorder effects in strong coupling superconductors. We use two different approaches, starting either from above or below the transition temper…
Effect of Magnetic Impurities on Suppression of the Transition Temperature in Disordered Superconductors
Robert A Smith, Vinay Ambegaokar
We calculate the first-order perturbative correction to the transition temperature in a superconductor with both non-magnetic and magnetic impurities. We do this by first eva…
The Upper Critical Field in Disordered Two-Dimensional Superconductors
Robert A Smith, Beccy S Handy, Vinay Ambegaokar
We present calculations of the upper critical field in superconducting films as a function of increasing disorder (as measured by the normal state resistance per square). In contra…
