Abstract
A superconducting article includes a substrate and a superconducting metal oxide film formed on the substrate. The metal oxide film including ions of an alkali metal, ions of a transition metal, and ions of an alkaline earth metal or a rare earth metal. For instance, the metal oxide film can include Rb ions, La ions, and Cu ions. The superconducting metal oxide film can have a critical temperature for onset of superconductivity of greater than 250 K, e.g., greater than room temperature.
Claims21
A superconducting article formed by a method comprising:
- forming, on a substrate, a metal oxide film including ions of an alkali metal and ions of a transition metal, and ions of one or more of an alkaline earth metal and a rare earth metal by atomic layer deposition, including:
- exposing the substrate to one or more pulses of a reactant including one or more of the alkaline earth metal and the rare earth metal;
- exposing the substrate to one or more pulses of a reactant including the transition metal;
- and
- exposing the substrate to one or more pulses of a reactant including the alkali metal;
- and
- annealing the substrate with the metal oxide film formed thereon.
