Abstract
The thermoelectric characteristics of carbon nanotubes are studied theoretically. The behavior of the differential thermal EMF of single-layer carbon zigzag-type nanotubes is studied in an external longitudinal dc electric field. The dynamics of the electron subsystem of the nanotubes is described using the Boltzman kinetic equation in terms of the quasi-classical approximation of relaxation times. The analytic relationship has been obtained for the differential thermoelectric coefficient and its nonlinear dependence on the field strength has been revealed.
