| Abstract: | We study theoretically the electron transport properties in carbon nanotubes under the influence of an external electric field () using Boltzmann’s equation. The current-density equation is derived. Negative differential conductivity is predicted when ≪ 1 (quasi-static case). We observed this in the neighbourhood where the constant electric field is equal to the amplitude of the AC electric field and the peak decreases with increasing . This phenomenon can also be used for the generation of terahertz radiation without electric current instability |
