This paper will explore the preparation methods of low-temperature superlattice YSZ/STO/YSZ-Al2O3 film and characterize its structure and properties. 1. Introduction: Low-temperature superlattice YSZ/STO/YSZ-Al2O3 film is a composite structure material composed of perovskite-type crystal YSZ and STO, which has good crystal matching and interface quality and is widely used in solid-state electronic devices. In this paper, the low-temperature superlattice YSZ/STO/YSZ-Al2O3 film is prepared by magnetron sputtering, and its structure and properties are characterized by X-ray diffraction, atomic force microscope, and electrical tests. 2. Experimental Method: The low-temperature superlattice YSZ/STO/YSZ-Al2O3 film was prepared on a Si substrate by magnetron sputtering. A layer of YSZ was first sputtered on the Si substrate as the bottom layer, and then STO and YSZ-Al2O3 were alternately stacked. During the sputtering process, the sputtering power, gas pressure, and substrate temperature were controlled to obtain a good film structure. After preparation, the film was characterized by X-ray diffraction, atomic force microscope, and electrical tests. 3. Results and Discussion: The low-temperature superlattice YSZ/STO/YSZ-Al2O3 film prepared by magnetron sputtering showed good crystallinity in the X-ray diffraction pattern, conforming to the perovskite-type structure characteristics. Atomic force microscope observation showed that the film surface was smooth and uniform, without obvious cracks and defects. Electrical tests showed that the film had low resistivity and high dielectric constant, indicating its potential application value. 4. Conclusion: The low-temperature superlattice YSZ/STO/YSZ-Al2O3 film prepared by magnetron sputtering has good crystallinity and surface quality. Its electrical properties make it very suitable for solid-state electronic devices. Further research can be carried out to control sputtering parameters and optimize film preparation processes to further improve film performance.
