Influence of Different Type of Irradiation
to Carbon Nanotubes
H. Yu. Mykhailova, I. Sydorchenko, V. Koda, and B. V. Kovalchuk
The study of radiation effects in CNT is due to the improvement and complementation of their properties during radiation exposure and high technological capabilities.
Insightful radiation not only causes radiation damage in materials but can also serve
as an effective technological tool for defects to improve the quality and obtain materials with fundamentally new properties. The electronic irradiation of MCNT at room
temperature results from the formation of vacancies on their walls and, ultimately,
by amorphization at high radiation doses, MCNTs are more stable to radiation than
SCNTs, probably because the atoms are knocked out of the internal ones. Radiation effects and radiation dose on the properties of carbon nanotubes have been
investigated in this article.
Carbon nanotubes (CNTs) attract the attention of scientists from many countries
of the world for the last 30 years. This interest is due to their unusual properties: they
combine high strength and elasticity, heat, and electrical conductivity. Mechanical
deformation and defects influence the electronic structure, concentration of charge
carriers, electrical, emission, and other properties of CNT. Defects arise both in
the process of synthesis (growth and gas admixtures) of CNT and with external
influences, especially in radiation. They reject the form of CNT from the rectilinear,
change the conditions of the passage of current, affect the concentration of charge
carriers, Fermi energy, and electrical conductivity.
The geometry of CNT varies under the action of elastic deformation, which can
significantly deform the profile of the entire nanotube, or locally in the region of
the intersection of contacting nanotubes, which affects the electronic structure at
the deformation point, which controls the electrical conductivity of not only one
