Websic feature of a carbon nanotube closely related to vibrations in all sp2 carbon mate-rials. The most important aspect of the G-band is the characteristic Raman lineshape which depends on whether the nanotube is semiconducting or metallic, allowing readi-ly distinguishing between both types. This band shows two components, the lower WebMWCNTs consist of multiple carbon nanotubes nested within one another. The number of nanotubes that are within a MWCNT can vary - from as little as 3, to over 20. At the same time the diameter of both the internal …
