ABSTRACT:
Disclosed is a superconducting Josephson junction which comprises a layer of niobium nitride on a substrate, an epitaxial layer of a pseudo-binary compound on the layer of niobium nitride, where the pseudo-binary compound has the composition about 3 atomic percent MgO--about 97 atomic percent CaO, to about 97 atomic percent MgO--about 3 atomic percent CaO, and an epitaxial layer of niobium nitride on the layer of pseudo-binary compound. Also disclosed is a method of making a Josephson junction by depositing a layer of niobium nitride onto a suitable substrate, depositing an expitaxial layer of a pseudo-binary compound onto the layer of niobium nitride, where the pseudo-binary compound has a composition of about 3 atomic percent MgO--about 97 atomic percent CaO, to about 97 atomic percent MgO--about 3 atomic percent CaO, and depositing an epitaxial layer of niobium nitride onto the layer said pseudo-binary compound.
