Our most recent work on ferroelectric/superconductor hybrids,  “High-Temperature-Superconducting Weak Link Defined by the Ferroelectric Field Effect” just appeared in Phys. Rev. Applied 7, 064015 (2017).

Josephson junctions are the cornerstones of numerous applications, and fabricating them from high-temperature superconductors has received much attention in recent years. It this work we exploit the local field-effect doping of a cuprate superconducting film by a ferroelectric overlayer, where domain structure is “written” at will using an atomic force microscope, to create a weak-link. The key advantage of this approach is that it creates Josephson junctions that are planar and can be reconfigured by “rewriting” the ferroelectric.
