Abstract: A method of fabricating a device including a superconductive layer includes depositing a seed layer on a substrate, exposing the seed layer to an oxygen-containing gas or plasma to form a modified seed layer, and after exposing the seed layer to the oxygen-containing gas or plasma depositing a metal nitride superconductive layer directly on the modified seed layer. The seed layer is a nitride of a first metal, and the superconductive layer is a nitride of a different second metal.

Abstract: A method of fabricating a device including a superconductive layer includes depositing a seed layer on a substrate at a first temperature, the seed layer being a nitride of a first metal, reducing the temperature of the substrate to a second temperature that is lower than the first temperature, increasing the temperature of the substrate to a third temperature that is higher than the first temperature to form a modified seed layer, and depositing a metal nitride superconductive layer directly on the modified seed layer at the third temperature, the superconductive layer being a nitride of a different second metal.

Abstract: A superconducting device includes a substrate, a metal oxide or metal oxynitride seed layer on the substrate, and a metal nitride superconductive layer disposed directly on the seed layer. The seed layer is an oxide or oxynitride of a first metal, and the superconductive layer is a nitride of a different second metal.
