Abstract: | The electronic properties of single-walled chiral carbon nanotube has been studied using the model based on infinitely long carbon atoms wrapped along a base helix of single-walled carbon nanotubes(SWNTs). The problem is solved semiclassically, and current density j , resistivity p, thermopower az and electrical power factor P calculated. It is noted that the current density j displays negative differential conductivity, whiles the resistivity p increases with increasing electrical field, p also slowly increases at low temperatures and then gradually increases with increasing temperature. The thermopower az shows interesting behavior. Very intriguing is the electrical power factor which shows relatively large values |
