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.

1. A method for forming a superconducting weak-link junction, the method comprising:
patterning a first junction bank, a second junction bank, 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, wherein the nanowire is at least one of shaped, sized, structured, located or connected to form a weak-link bridge between the first junction bank and the second junction bank.
