different from nanowire samples. From the elemental mapping, it was confirmed that
the tips of the tubes contained the Fe catalyst. The conclusion is that small changes
in the experimental parameters of the plasma process leads to drastic changes in
the product morphology and other properties. The XRD spectra shown in Fig. 9
