Nb/sub 3/Ge superconductive films grown with air

Patent ·
OSTI ID:5905725
A superconductive film of Nb/sub 3/Ge is produced by providing within a vacuum chamber a heated substrate and sources of niobium and germanium, reducing the pressure within the chamber to a residual pressure no greater than about 10/sup -5/ mm Hg, introducing air into the resulting evacuated chamber in controlled amounts and vaporizing the niobium and germanium to deposit a film of Nb/sub 3/Ge on the heated substrate.
