Electron Tunneling in Superconducting Cd-Al2O3-Al Junctions Academic Article uri icon

abstract

  • Studies were performed of the superconducting tunneling characteristics of Cd-Al2O3-Al junctions. The superconducting energy gap 2cd(0) was found to be 0.130 mV. Its variation with temperature was studied and has been compared with the predictions of the BCS theory. Measurements were also made in the presence of magnetic fields, and an effort was made to compare measurements with the Ginzburg-Landau theory. Extra structure in the first derivative of the tunneling characteristics (dVdI versus V) was observed, and experiments were undertaken to ascertain whether this structure was caused by edge effects in the films or was a more basic feature of the films. 1969 The American Physical Society.
