Abstract : |
In this work the STM investigation of nanotube point defects created by ion irradiation (e.g. vacancies) is
presented. The defects appeared as hillock-like features on the STM images. These defects were compared
with similar features observed on the STM images of as-grown coiled carbon nanotubes. In this case the
observed hillock-like features were attributed to the non-hexagonal carbon rings, which are responsible
for the growth of bent and coiled nanotube structures. For irradiation, multi-walled carbon nanotubes
produced by the arc-discharge method were dispersed on highly oriented pyrolitic graphite (HOPG) surface
and irradiated with Ar+ ions of 30 keV, using a low dose of D = 5 × 1011 ions/cm2. |
