Analysis of the Proximity Effect on Niobium Superconducting Resonators

The proximity effect is a phenomenon in which superconductivity penetrates a normal, non-superconducting metal across a distance as long as the coherence length of the material. Some research has noted that the proximity effect can significantly increase the critical superconducting temperatures of superconductors. My research focuses on analyzing the interplay between two different types of thin-films (Titanium Nitride and Gold) on Niobium superconducting resonators and analyzing the serious effects that these thin-films have upon the emergence of the proximity effect and how that affects the superconducting characteristics of the resonators. I focus specifically on the superconducting and normal metal bilayers (S/N) and manipulate four different variables of magnetic field, transference, film thickness, and resonator temperature, to study the effects that such changes have on the two different types of bilayers and their overall effect on the superconducting resonators.
