| Zusammenfassung: | X1-x3 A method of forming PrCaMnOthin films having a PMO/CMO super lattice structure using metalorganic chemical vapor deposition includes preparing organometallic compounds and solvents and mixing organometallic compounds and solvents to form PMO and CMO precursors. The precursors for PMO and CMO are injected into a MOCVD chamber vaporizer. Deposition parameters are selected to form a nano-sized PCMO thin film or a crystalline PCMO thin film from the injection of PMO and CMO precursors, wherein the PMO and CMO precursors are alternately injected into the MOCVD chamber vaporizer. The selected deposition parameters are maintained to deposit the PCMO thin film species having a desired Pr:Ca concentration ratio in a specific portion of the PCMO thin film. The resultant PCMO thin film is annealed at a selected temperature for a selected time period. |
