Abstract
There is considerable interest in the fabrication of all refractory Josephson junctions with high T electrode material.1–4 Among the high Tc refractory materials, NbN offers several advantages in addition to its high Tc ~16 K. Films of NbN are easily deposited by reactive sputtering in a clean vacuum system without intentional substrate heating.5,6 These films are mechanically stable, cycle well and devices fabricated from these films have the potential for operation at temperatures near 10 K where small closed cycle refrigerators are becoming available. Devices fabricated from these materials have applications as magnetometers, millimeter wave detectors and mixers, digital devices and in signal processing.
