摘要：

Skutterudites (SKDs) are promising thermoelectric (TE) materials due to their cost-effectiveness and favorable electrical properties. However, their high thermal conductivity limits thermoelectric conversion efficiency. Herein, Y2O3 nanoparticles (NPs)-decorated n-type Yb0.3Co4Sb12 were prepared by spark plasma sintering (SPS). The heterointerfaces created by Y2O3 nanoparticles enhance charge carrier localization through O-Sb hybridization and O-Co bonding, which increases the Seebeck coefficient. Additionally, heterointerfaces scatter phonons, reducing thermal conductivity. Consequently, a figure of merit (ZT) value of similar to 1.48 at 773 K and an average ZT(ave) of similar to 1.0 (293-823 K) were achieved in this work.
