Low-Temperature Growth of Large Area, Vertically Aligned Carbon Nanotubes for Field Emission Applications
Large area, highly uniform vertically aligned carbon nanotips (VACNTP) and other nanostructures have been grown on silicon (100) substrates with Ni catalyst in the low-temperature, lowfrequency, high-density inductively coupled plasmas (ICP) of methane-hydrogen-argon gas mixtures. The control strategies for the morphology, crystalline structure and chemical states of the resulting nanostructures by varying the growth conditions are proposed. XRD and Raman analyses confirm that the nanotips are well graphitized, which is favorable for the field emission applications.
