Familiarity with the characteristics of electronic transmission or conductivity of nanotubes (single and multi-walled) CNTs and CNTs (based on PhD in nano-microelectronics)

 Note:  In the case of electronic transmission and conduction  , different molecules on the surface of CNTs nanotubes have similar conditions in terms of the length of SWCNTs and their hardness. There are many properties and applications of carbon nanotubes that take full advantage of CNTs aspect ratio, mechanical strength, electrical and thermal conductivity.

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 loses its sensitivity  to electronic conductivity,  while it is sensitive to the electronic evolution of carbon nanotube particles in the mode of transmission or electrical conductivity  Therefore, some intrinsic 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 state of potential conductivity and electron conduction.

In nanoelectronics, he used the arc method to produce carbon nanotubes. This method uses an almost low voltage source to create a spark between the two electrodes. Intermediate metal catalysts are added to the graphite anode to accelerate the production of carbon nanotubes. Nanotubes can usually be added to their mass to improve the electrical properties of some materials, such as  GCE (carbon glass electrodes)  , carbon paste  electrodes, graphite electrodes, or graphene electrodes  In general, it has been observed that the  addition of nanoparticles into the structure of the electrodes leads to  improved electrochemical properties, higher sensitivity and less diagnostic limitations  In addition, in nano- electrochemical detection methods  , the use of nanostructures generally causes  Improves charge transfer at the electrode surface.

Conclusion : 

In the case of electronic transmission and conduction  , different molecules on the surface of CNTs nanotubes have similar conditions in terms of SWCNT length and stiffness. There are many properties and applications of carbon nanotubes that take full advantage of CNTs aspect ratio, mechanical strength, electrical and thermal conductivity.
