Twisted small organic molecules for high thermoelectric performance of single-walled carbon nanotubes/small organic molecule hybrids through mild charge transfer interactions

Abstract

Twisted small organic molecules (SOMs) enhance the thermoelectric performance of single-walled carbon nanotubes (SWCNTs)/SOM hybrid films by dramatically increasing the Seebeck coefficient and minimising the inevitable reduction in electrical conductivity. This is due to the mild charge transfer interactions between the SWCNTs and SOMs, which facilitate charge carrier transport between them.
