Researcher and author: Dr. ( Afshin Rashid)
Note: CNTs and CNT carbon nanotubes are highly sensitive to oxygen in reverse . Adding a small amount of oxygen to these nanotubes can reverse their electrical resistance, so semiconductor nanotubes can turn into metal nanotubes due to the presence of oxygen.
Electronic conductivity can affect some of the intrinsic properties of these nanotubes . Heat treatment on nanotubes reduces the number of structural defects in nanotubes, which are caused by purification or catalyst particles. After heat treatment, the electronic spectrum of CNT single-walled carbon nanotubes lost its sensitivity to electronic conductivity while it is sensitive to the electronic evolution of carbon nanotube particles in the reverse mode . Therefore, some inherent properties for pure nanotubes or those that are slightly heated are subjected to the reaction of electromagnetic particles and the increase in conductivity in the reverse state.
Functionalization of the side wall of nanotubes leads to better bonding of specific compounds with nanotubes and also improves the sensitivity and electronic conductivity of CNT and CNTs carbon nanotubes. This charge transfer important information about electronic call in Reverse nano clusters on electron transport in nanotubes are frequent affect the possibility of controlling the shape, dimensions, electrical resistivity and electromagnetic influence of nanoparticles on the nanotubes reverse the .
Conclusion:
Carbon nanotubes CNTs and CNTs are highly sensitive to oxygen in the reverse or electronic reverse mode . Adding a small amount of oxygen to these nanotubes can reverse their electrical resistance, so semiconductor nanotubes can turn into metal nanotubes due to the presence of oxygen.
