In its superconducting state, MoTe2 displays oscillations arising from an edge supercurrent, and when it is near niobium, there is an incompatibility between electron pairs diffusing from niobium and the pairs intrinsic to MoTe2. Insight into this competition between pairs is obtained by monitoring the noise spectrum of the MoTe2 supercurrent oscillations.
