ABSTRACT
Two-dimensional carbon nanostructures (carbon nanowalls) were fabricated using capacitively coupled radio-frequency plasma-enhanced chemical vapor deposition assisted by H radical injection. Carbon nanowalls were grown on Si, SiO2, and sapphire substrates without catalyst, and independent of substrate materials. Correlation between carbon nanowall growth and fabrication conditions, such as carbon source gases was investigated. In the case using C2F6/H2 system, aligned carbon nanowalls were grown vertically on the substrate, while carbon nanowalls grown using CH4/H2 system were waved and thin (<10 nm). In the case of the deposition without H radical injection, on the other hand, carbon nanowalls were not fabricated. © 2004 American Institute of Physics.
