Abstract :
Carbon nanotubes (CNTs) have been grown on glass substrate coated with metal catalysts containing Ni by microwave plasma enhanced chemical vapor deposition using mixtures of methane and hydrogen. In addition TiN metal was coated buffer layer between Ni layer and glass substrate. CNTs growth length increased with deposited process pressure. SEM (scaning electron microscopy) and TEM (transmission electron microscopy) image show CNTs diameter and density are varied with deposition conditions. Raman spectroscopy of CNTs show that D-band and G-band peak positions around 1370 cm-1 and 1590 cm-1.
