- Abstract
- A novel double-layer nanostructure of silicon carbide and tungsten oxide is synthesized by a two-step thermal evaporation process using NiO as the catalyst. First, SiC nanowires are grown on Si substrate and then high density W18O49 nanorods are grown on these SiC nanowires to form a double-layer nanostructure. XRD and TEM analysis revealed that the synthesized nanostructures are well crystalline. The growth of W18O49 nanorods on SiC nanowires is explained on the basis of vapor-solid (VS) mechanism. The reasonably better turn-on field (5.4 V/mu m) measured from the field emission measurements suggest that the synthesized nanostructures could be used as potential field emitters.
