Diameter of carbon nanotube formula
WebThe carbon nanotube structure as shown in Figure 2a is replaced by the effective reinforcing element in Figure 2b. The diameter 2Rn of the SWCN is a strong function of the chiral integers n and m and varies over a wide range as shown in Table 1. However, it is the smaller diameters of Webtube, as well as the diameter of the tube, will determine many physical properties; tubes can be insulating, semiconducting, or metallic. When multiple layers of graphite are rolled into a single tube, the resulting structure is called a Multi-Walled Carbon Nanotube (MWNT). ω Fig.1: Illustration of the structure of a single walled carbon
