	abstract = {<div>Using a tight-binding calculation, we explain the origin of a large thermopower <em>S</em> in ropes of single-walled carbon nanotubes. We have shown that, by breaking the symmetric energy bands and increasing the overlap energy γ0, a larger <em>S</em> can be obtained. We have also found that a 10\% increase in γ0 resulted to a thermopower that is four times as large.</div>},

	abstract = {This paper aims to study the diffusion thermoelectric power of singe-walled carbon nanotubes (SWNTs). This was obtained using a linear response method and a semiclassical treatment of metallic-like systems. The energy and the density of states were generated using the tight binding model for both electrons and holes. The SWNT, exhibiting a diffusive transport, is shown to have a negative thermoelectric power for an energy-dependent relaxation time. This indicates that electrons are dominant and demonstrates a metallic-like behavior.},
