Synthesis of Aligned Carbon Nanotubes by dc Plasma-Enhanced Hot Filament CVD.

Original language description

Vertically aligned carbon nanotubes (CNTs) films have been prepared by a direct current plasma-enhanced hot filament chemical vapour deposition method. The growth of multi-walled carbon nanotubes on metal (Fe, Co, Ni) precoated silicon substrate are studed between 500 and 1000degreesC using gas mixtures of methane, hydrogen and argon. The influence of substrate pre-treatment, substrate voltage and deposition temperature on the structure and the alignment of the CNTs are discussed. In dependence on thickess of the thin metal layers, thermal pre-treatment or hydrogen plasma etching and plasma parameters during the deposition process different carbon nanostructures, especially regarding tube diameter, morphology and arrangement could be proved. Transmissin electron microscopy images of isolated tubes showed an imperfectly trained tubular structure of graphite shells, formed as 'bamboo'-like shapes with partly crystalline metal droplets on the tip. Because the alignment of the tubes is ind
