Abstrakt

The growth process of inner-shell tubes from C₆₀ peapods and ferrocene (FeCp₂)

filled single-wall carbon nanotubes was studied with Raman spectroscopy

and X-ray diffraction (XRD). In the peapod case, it is shown that the

Raman signal of the fullerenes decays about a factor five faster than

the XRD peak of the 1D fullerene chain. The growth of the inner-shell

tubes coincides well with the 1D chain decay. In the FeCp₂

case, the inner tubes grow already at 600 °C in about one hour.

Additionally, even for the same starting material, the inner-outer tube

pair distribution is different than for C₆₀ based inner tubes.
