| Abstract: | The generation of higher harmonics by semiconductor carbon nanotubes in the presence of constant electric field polarized
along the nanotube axis is considered. The analysis is performed in the semiclassical model of electron motion without taking
into account interband transitions. The electron system of carbon nanotubes is described using the kinetic Boltzmann equation
in the relaxation time approximation. The dependence of higher harmonic amplitude on the field characteristics is studied. |
