Study on the application of manganese silicide

Transition metal silicides are a class of refractory intermetallic compounds, which have been successfully applied in complementary metal oxide semiconductor (cmos) components, thin film coatings, block structure components, electrothermal components, thermoelectric materials and photovoltaic materials due to their unique physical and chemical properties.Its nanomaterials show special electrical, optical, magnetic and thermoelectric properties, and even have potential applications in the field of catalysis.

The formation of manganese silicide films throughout thermal hardening of Mn/Si structures is studied. The temperature vary of compound formation is decided. Between four hundred and 800°C, the reaction between Mn and Si yields MnSi. The samples toughened at 800–1000°C accommodates MnSi and therefore the higher atomic number 25 compound MnSi1.75. on top of 1000°C, the films accommodates MnSi1.75and the metal-rich part Mn5Si3.

We report the synthesis, structural identification, and electrical properties of the primary one-dimensional (1-D) nanomaterials of a semiconductive higher manganese silicide (MnSi2−x) with widths all the way down to ten nm via chemical vapor deposition of the single-source precursor Mn(CO)5SiCl3. The complicated Nowotny chimney ladder structure of those homologous higher manganese silicides, conjointly said as MnnSi2n−m, MnSi1.75, or MnSi1.8, contributes to the superb thermoelectrical performance of the majority materials, which might be increased by phonon scattering because of 1-D nanoscale pure mathematics. The morphology, structure, and composition of MnSi2−x nanowires and nanoribbons area unit examined exploitation microscopy and X-ray qualitative analysis. Elaborate choose space lepton optical phenomenon analysis on single-crystal nanowires reveals the part to be Mn19Si33, one amongst a series of crystallographically distinct higher atomic number 25 silicides that have a Nowotny chimney ladder structure. Electrical transport study of single nanowires shows that they're degenerately doped with a coffee electrical resistance (17 mΩ•cm) kind of like the majority.
