Electronic excitation induced modifications in elongated iron nanoparticle encapsulated multiwalled carbon nanotubes under ion irradiation

The TEM image describes the formation of defects and changes in the MWCNT after the irradiation with 120 MeV Ag ions. The upshift in the G mode peak position with the increase in fluence is shown along with the relation between buckling wavelength (λ) with diameter of CNT fitted with exp(r0.5), solid line is the fitted curve and the points (stars and triangles) indicate the experimental data for MWCNT samples with and without embedded Fe nanorods.
