Claim Text:
1. A method for producing pure phase strontium ruthenium oxide films, the method comprising: a. solubilizing a non-chlorinated ruthenium-containing compound with a first solvent to form a first solution and a non-chlorinated strontium-containing compound with a second solvent to form a second solution, wherein the first and second solvents are different, and wherein the first and second solvents form ligands less than 4 carbons in length; b. combining the first solution and second solution into a single mixture; c. subjecting the mixture to a first temperature above that necessary for forming strontium ruthenium oxide while simultaneously preventing formation of RuO d. maintaining the first temperature for a time to remove organic compounds from the mixture, thereby forming a substantially dry film; and e. subjecting the film to a second temperature higher than the first temperature for time sufficient to crystallize the pure strontium ruthenium oxide film in the perovskite crystal structure.
