Abstract: | Within the context of electronic transport in a single-walled carbon nanotube, electron velocity (Fermi velocity) is calculated by using a particle-in-a-box model and assuming a prototype single-wall tube in which the Fermi velocity is the average value of the electron velocity as a function of the tube radius when all the possible radii are considered. The result of this calculation is compared with the well-known result obtained from a tight-binding approximation and with experimental data. |
