SrRu1−xFexO3 films coated with SiO2 nano-particles

Abstract The SrRu 1− x Fe x O 3 films ( x =0.0, 0.1, 0.3, 0.5) were successfully fabricated using the powders coated with SiO 2 nano-particles (≈30 nm). The SrRu 1− x Fe x O 3 powders (≈500 nm) were synthesized by a conventional solid-state reaction. Thanks to the fused SiO 2 nano-particles in the vicinity of the glass softening temperature at approximately 700 °C, the SrRu 1− x Fe x O 3 powders are strongly attached onto the surface of the glass substrate. The various techniques were performed to characterize the films, such as X-ray photoelectron spectroscopy, field emission-scanning electron microscopy, Mossbauer spectroscopy and resistivity measurements. This simple and low-cost method to get the SrRu 1− x Fe x O 3 films ( x =0.0, 0.1, 0.3, 0.5) may promise for applications to microelectronics field, such as dynamic random access memory or ferro-electric random access memory.
