Silicided nanowires for nanobridge weak links

摘要

Silicided nanowires as nanobridges in Josephson junctions. A superconducting silicided nanowire is used as a weak-link bridge in a Josephson junction, and a fabrication process is employed to produce silicided nanowires that includes patterning two junction banks and a rough nanowire from a silicon substrate, reshaping the nanowire through hydrogen annealing, and siliciding the nanowire by introduction of a metal into the nanowire structure.
