Summary: This article investigates the effect of multiwalled carbon nanotube (MWCNT) inclusions on the thermoelectric performance of Cu3SbS4. The results demonstrate that adding an optimal amount of MWCNT inclusions significantly improves the Seebeck coefficient and reduces the thermal conductivity of Cu3SbS4. The optimized composite sample achieves a maximum figure of merit (ZT) of 0.43 at 623 K, which is 70% higher than pristine Cu3SbS4. In addition, the addition of nanoinclusions also enhances the mechanical stability of the samples.
