High yield synthesis and growth mechanism of carbon nanotubes

Abstract With Y 2 O 3 /carbon composite rods, Carbon nanotube bundles were synthesized in high yield by d.c. arc-vaporizing method. The carbon nanotube bundles and carbon nanotubes were observed by optical microscope, scan electron microscope and high-resolution transmission electron microscope. According to our observations, a new model is proposed to account for the growth of cathode deposit with nanotube bundles.
