Abstract
Disclosed is a method for fabricating an edge geometry superconducting tunnel junction device comprising two niobium nitride superconducting electrodes (14,28) and a magnesium oxide tunnel barrier (24) sandwiched between the two electrodes. The NbN electrodes are preferably sputter-deposited, with the first NbN electrode deposited on an insulating substrate maintained at about 250.degree. to 500.degree. C. for improved quality of the electrode.
