| Summary: | The structure of multi-walled carbon nanotubes exposed to a
pulsed high-power ion beam is investigated using the methods
of Raman spectroscopy and transmission electron microscopy.
It has been shown that irradiation with an ion beam generates
significant defects in the structure of nanotubes. With an increase
in the number of pulses, processes associated with the annealing
of defects in the internal structure of the samples are observed.
Electron microscopy data make it possible to distinguish two
types of defects leading to a decrease in the interlayer distance of
the carbon nanotube wall. |
