Abstract

In this paper, the Seebeck effect of mutilwalled carbon nanotube films has been studied. The carbon nanotubes were synthesized by hot filament chemical vapor deposition using Ni - Fe as a catalyst. It was found that the thermoelectromotive force (thermo emf) changed approximately linearly with the temperature at the hot end at room temperature, and the Seebeck coefficient of carbon nanotube films was about 10~50 μv/k. The experimental results were discussed in detail.
