Phonon and thermoelectric properties of single- and double-walled carbon nanotubes from first principles

The phonon and thermal properties of different single- ((n,0) (n = 7,8,9,10,14,15)) and double-walled carbon nanotubes ((7, 0) @ (14, 0), (8, 0) @ (14, 0), (9, 0) @ (15, 0) and (10, 0) @ (15, 0),) were calculated using the combination of density functional theory and non-equilibrium Green’s function methods. It was found that the Seebeck and Peltier coefficients for some of the single- and multi-walled carbon nanotubes have negative values. Moreover, in sharp contrast to low ?T, the higher thermoelectric figure of merit is anticipated at the higher temperature. The effect of the atoms number per unit cell on the phonons energies outweighs the effect of the vacuum and the size of the tubes for DWCNTs. All in all, the electron–phonon coupling generates the roughly plethora of thermoelectric coefficients and thermal conductance.
