Enhanced thermoelectric performance of SWNT/organic small molecule (OSM) hybrid materials by tuning of the energy level of OSMs

Abstract

Energy level modulation of organic small molecules (OSMs) enables significant enhancement in the Seebeck coefficient and power factor (PF) of single-walled carbon nanotube (SWNT)/OSM hybrids. The highest TE performance of the hybrid was achieved by lowering the energy barrier between SWNT and OSM and thus facilitating energy-filtering.
