Abstract
Carbon helix nanofibers were synthesized by a hot filament assisted chemical vapor deposition at a substrate temperature of 600 °C. It was observed that the formation of a carbon helix structure was attributed to the mixing of cobalt catalyst particles with copper. The diameter of carbon helixes varied from 20 to 500 nm. The growth mechanism and the structure of these carbon helix nanofibers are discussed based on scanning electron microscopy and Raman spectroscopy measurements.
