A Review of Chirality Finding Techniques of DWCNT
Keywords:Chirality, Characterization, Nanotube, Double walled.
Double Walled Carbon Nanotube has shown remarkable electrical and mechanical properties. However, their characterization has been a great challenge. Different techniques previously existed for finding the chirality of carbon nanotube. But implementing those techniques for double walled carbon nanotube represents various challenges due to interaction between the tubes and change in the optical and electrical properties. In this work, for the first time we represent a complete overview of the possible techniques proposed in finding the chirality of Double walled carbon nanotube. Additionally we compare their relative advantages and disadvantages taking accuracy, feasibility and other factors into account.
