Abstract

We have investigated the synthesis and field emission properties of high-quality double-walled carbon nanotubes (DWCNTs) using a catalytic chemical vapor deposition method. For the synthesis of DWCNTs using a catalytic CVD method, we used various carbon containing molecules such as methane, ethylene, THF and propanol over Fe-Mo embedded MgO support material. The produced carbon materials using a catalytic CVD method indicated high-purity DWCNT bundles free of amorphous carbon covering on the surface. DWCNTs showed low turn-on voltage and higher emission stability compared with SWCNTs.
