Resumen

A dense carbon nanotube [CNT] forest was formed by chemical vapor deposition [CVD] using spin-coated iron oxide (Fe2O3) thinfilm on Si substrate. The nanoforest contains carbon nanotubes was obtained by feeding a mixture of acetylene, hydrogen and nitrogen [N2:H 2: C2H2 D 27: 27: 5 mL/min] for 45 min at 700°C in the CVD chamber. The CNT forest was subjected to analyze the phase, crystalline quality and microstructure using X-ray diffraction, Raman spectroscopy, and scanning electron microscopy [SEM], respectively. The elemental analysis and mapping were also studied using energy dispersive X-ray spectroscopy [EDX]. The morphology, shape and size of the nanotubes were characterized by transmission electron microscopy. The obtained carbon nanotubes were of length 13-14 mm and diameter of 10-100 nm over Fe thin-film coated on Si substrate, which makes this CNT/ Fe/Si hybrid material could be a better candidate for field emission applications.
