Properties And Structures Of Single Walled Carbon Nanotubes (SWNT’s)
Single Walled Carbon nanotubes | Image Resource : carbonallotropes.com Carbon nanotubes (CNTs) are a recent development that has found its utility and application in a variety of spheres of work. The nanotubes consist up to several tens of graphite shells. SWNT’s can be produced by three major techniques: arc discharge, laser ablation and catalytic growth. The nanotubes are suitable as electron field emitters because of their Nano size, high electrical conductivity, and structural perfection. These also find their application in electronic devices such as field effect transistors. Nanotubes and much information about them Initially, the preparation of the nanotubes consisted of needle-like tubes that were produced using arc discharge that is similar to the fullerene synthesis that takes place in an argon filled vessels. On a large scale, it can be produced by using the CVD technique and iron as a catalyst. Single Walled Carbon nanotubes were formed on the substrate cont...
