Abstract

Using a tight-binding calculation, we explain the origin of a large thermopower S 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 S can be obtained. We have also found that a 10% increase in γ0 resulted to a thermopower that is four times as large.
