Theory and Measurements on Lead—Tellurium—Lead Supercurrent Junctions
We previously reported1 the fabrication of lead—tellurium—lead Josephson junctions which exhibit uniform current distribution in the junction. Supercurrent has been observed for barriers having thicknesses up to 800 Å. The critical current dependence on tellurium thickness and temperature were also reported. Here we give a theoretical derivation of the critical current as a function of tellurium thickness and temperature.
