Abstract

In this paper, the carrier statistics in the carbon nanotube with nonparabolic energy spectrum was investigated to predict the ultimate (intrinsic) drift velocity using Arora´s formalism, as a function of temperature, concentration, and chirality. Quantum emission factor was also explored. Results stated that the quantum emission does not affect the CNT mobility but lowered the saturation velocity. Results on ballistic and scattering-limited transport were also presented in order to identify experimental planning for the correct mechanisms of CNT or graphene nanostructure.
