Abstract: Despite the small or near-zero Seebeck coefficient of metallic nanotubes, a nanotube film can be readily scaled up in length. Thus so can its thermoelectric power. In this work, we inserted a nanomesh pattern into a carbon nanotube film by using an anodized aluminum oxide membrane as an etching mask. We found that by patterning densely packed nanoscale holes into the nanotube film, its total thermoelectric power can be further increased, by as much as 30% (from 29 to 39 μV K(-1)). We present this finding, attributed to electron localization due to nanopatterning, as indicative of the potential of a new degree of freedom.
