Investigation of the Formation of Fe-filled Carbon Nanotubes

Reuther, H.; Müller, C.; Leonhardt, A.; Kutz, M. C.

The formation of Fe-filled carbon nanotubes by thermal decomposition of ferrocene combined with a Fe-catalyst-nanostructuring on an oxidized Si substrate is investigated in the temperature range of 1015 – 1200 K. The optimal growth conditions for aligned and homogeneous carbon nanotubes are found at 1100 K. Mössbauer spectroscopy (both in transmission geometry and CEMS) was used to analyze and quantify the different formed Fe-phases. In general, a-Fe, g-Fe and Fe3C are found to form within the carbon nanotubes. Depending on the growth conditions their fractions vary strongly. Moreover, an alignment of the a-Fe in the tubes could be detected.
