Method of using thermoelectric device

摘要

A method using an apparatus includes the following steps. Providing a thermoelectric composite material, and establishing a sufficient temperature gradient in the thermoelectric composite material to create a voltage. The thermoelectric composite material includes a carbon nanotube structure comprising a plurality of carbon nanotubes and a plurality of spaces defined by and between the carbon nanotubes, and an electrically conductive polymer layer coated on the carbon nanotube structure.
