Giant thermoelectric power in fluorine-doped single-walled carbon nanotubes

Herein, we report on a tunable axial thermoelectric power (TEP), in a non-degenerate fluorine-doped single-walled carbon nanotubes (FSWCNTs) as calculated for carriers in the lowest miniband using a tractable analytical approach. We deduced the axial thermoelectric power (α_zz) as a function of temperature gradient (∇T). Additionally, we investigated the influence of doping concentration (n_o), constant electric field (E_o), and overlapping integral for jumps (Δ_s and Δ_z) on their behaviour. The intensity of the axial thermoelectric power (α_zz) and the operational temperature range could be tuned using the constant electric field, doping and overlapping integrals, respectively. It is worth noting that the giant thermoelectric power (α_zz) obtained and the ability to tune the FSWCNT to operate at high temperatures make FSWCNT a potential candidate for thermoelectric applications such as remote power generation.
