Carbon Nanotube Thermoelectric Coolers

Abstract

The primary purpose of this project was studying of the thermoelectric Peltier cooling in carbon nanotube nano-circuits. The success of this work was based on strong coupling of the experimental and theoretical research. Thermoelectric effect was measured using two sequentially-connected carbon nanotube (CNT) field-effect transistors (FETs), each with charge carriers of opposite sign, either electrons or holes, whose concentration is controlled by the side gate electrodes. A change of the intrinsic temperature, T, inside the CNT owing to the thermoelectric effect is determined from the change of the position and width of spectral singularities manifested in the experimental curves of the source-drain electric conductance. Inside the central section of the carbon nanotube, we obtained an impressive Peltier cooling 57 K down from the liquid nitrogen temperature.
