Niobium-based superconducting nano-devices fabrication using all-metal suspended masks [PDF]
, 2013 We report a novel method for the fabrication of superconducting nanodevices based on niobium. The well-known difficulties of lithographic patterning of high-quality niobium are overcome by replacing the usual organic resist mask by a metallic one.
