Thermoelectric power of single walled carbon nanotubes containing alcohol molecules

Thermoelectric power, S ( T ), for single walled carbon nanotubes (SWNT) shows a strong curved T -dependence. The results of S ( T ) are interpreted as the effect of the interaction between conduction electrons and transition metals; i.e. Kondo effect. However, for SWNT containing alcohol molecules such as methanol or ethanol, the S ( T ) is almost proportional to T . The results indicate the characteristic metallic behavior in SWNT doped with O 2 .
