Imaging the Superconducting Proximity Effect in S-S'-S Transition Edge Sensors

Austin R. Kaczmarek, Samantha Walker, Jason Austermann +11

Proximity effects at superconducting interfaces, between different superconductors (S-S') or between superconductors and normal metals (S-N), are fundamental to the performance of…

Can slow recombination in ordered superconductors explain the excess quasiparticle population?

Eva Gurra, Douglas A. Bennett, Shannon M. Duff +2

An excess density of quasiparticles is widely observed in superconducting films. This excess causes performance degradation in a variety of superconducting devices, including decoh…

Direct Imaging of Transition-Edge Sensors with Scanning SQUID Microscopy

Samantha Walker, Austin Kaczmarek, Jason Austermann +10

Significant advancements have been made in understanding the physics of transition-edge sensors (TESs) over the past decade. However, key questions remain, particularly a detailed…
