Abstract
Carbon nanotubes (CNTs) were grown by chemical vapor deposition (CVD)
method. FeCl3 was used as the precursor of iron which acts as the catalyst
.Solution of FeCl3 in ethanol at concentration of (0.05 mole/litter) has been
chosen. Silicon (100) substrates were spin- coated with the prepared catalyst
solution (FeCl3) .Carbon nanotubes were grown on Si (100) substrate coated with
catalyst in tube furnace using argon and acetylene gases at temperature of 750°C
for 30 minutes. The structures of the produced material were characterized with
Raman spectroscopy and FESEM. Raman spectra showed MWCNTs with the
presence of radial breathing mode (RBM) at low frequency. The morphology of
carbon nanotubes called noodles–like CNTs with an average diameter of 45nm
was observed with FESEM micrograph.
