Synthesis of Carbon Nanotubes Using Hydrocarbon Ion Beams

Abstract:

Toward the tailored growth of carbon nanotubes (CNTs), CNT growth using hydrocarbon ion beams at the ion energy of 150 eV and the ion current densities of 10 ∼ 165 μA/cm2 was challenged at various growth temperatures. Fibrous protrusions with an amorphous nature grew at a low ion current density, whereas highly crystallized multi-wall CNTs were synthesized at high ion current densities. The higher the growth temperature and the ion current density, the smaller the CNT diameter. Similar to the conventional PECVD-grown CNTs, they grew via the so-called “tip-growth mode.”
