Electrical and mechanical properties of bonded superconducting interfaces
PhD - Leuven | Just now
Interfaces between (different) superconductors are important for continuous, superconducting links between different layers in a future cryogenic system. For conventional bonding approaches, IMCs can interrupt superconductivity, while dissimilar superconductors can result in complex quasiparticle dynamics. This PhD will study, in depth, the interface between superconductors using a variety of techniques, focusing on both mechanical and electrical behavior.
