摘要：

In a recent letter Tyagi [Appl. Phys. Lett. 86, 253110 (2005)] have reported the special orientation of nickel planes inside multiwalled carbon nanotubes (MWCNTs) with respect to the tube axis. Heavy ion irradiation has been performed with 1.5 MeV Au2+ and 100 MeV Au7+ ions on these nickel filled MWCNTs at fluences ranging from 10(12) to 10(15) ions/cm(2) at room temperature. Ion-induced modifications have been studied using high-resolution transmission electron microscopy. The diffraction pattern and the lattice imaging showed the presence of ion-induced planar defects on the tube walls and completely amorphized encapsulated nickel nanorods. The results are discussed in terms of thermal spike model. (c) 2006 American Institute of Physics.
