A titanium (Ti) seed layer is formed from a Ti source directly on a surface of a substrate, where the surface is substantially free of oxide and nitride, and a reactive nitrogen species is introduced from a nitrogen plasma source and additional Ti is introduced from the Ti source, wherein the nitrogen plasma: (a) reacts with the Ti seed layer to form TiN and (b) reacts with the additional Ti to form additional TiN. The TiN and additional TiN collectively form a TiN superconducting layer that directly contacts the surface of the substrate.
