Characteristics of Nb/Al superconducting tunnel junctions fabricated using ozone gas |
Relationship between J C and O3 exposure in the O3 process for indirect (solid circles) and direct (open circles) spray of the gas. The solid and dashed lines are fit to the data for indirect and direct spray of the gas, and indicate the dependencies J C ∝ ( Pt )− 1.2 and J C ∝ ( Pt )− 0.6, respectively. |
