Synthesis and characterization of Tin Oxide nanostructures at atmospheric pressure

We report the synthesis of Tin Oxide (SnO₂) nanostructures on Silicon substrate and gold coated Silicon substrate by thermal evaporation method using a mixture of SnO₂ and graphite powders at 1100°C in nitrogen (N₂) ambience at atmospheric pressure. The synthesized SnO₂ nanostructure shows polycrystalline nature with tetragonal phase. The SnO₂ nanowires with uniform diameter (~35 nm) and length (~30 μm) grows with vapor-liquid-solid mechanism on the gold coated Silicon substrate whereas, the SnO₂ nanorods with varying diameter grows with vapor-solid mechanism on the uncoated Silicon substrate.
