Enhanced Thermoelectric Performance of Cu2Se via Nanostructure and Compositional Gradient

Lin Bo et al.

Summary: Forming co-alloying solid solutions is an effective strategy for improving thermoelectric performance. In this study, dense Cu2-x(MnFeNi)(x)Se samples with intrinsically low thermal conductivity were prepared, and the influences of nanostructure and compositional gradient on the microstructure and thermoelectric properties of Cu2Se were evaluated. The results showed a decrease in thermal conductivity and an increase in zT value for the Cu-1.91(MnFeNi)(0.09)Se sample.

In-situ growth of carbon nanotubes on ZnO to enhance thermoelectric and mechanical properties

Shengjie Fan et al.

Summary: This study developed a method to achieve in-situ growth of uniform carbon nanotubes (CNTs) on zinc oxide (ZnO) nanoparticles using chemical vapor deposition technology. Magnetic nickel nanoparticles were introduced as catalysts to promote CNT formation and enhance the electrical and thermal conductivity of ZnO matrices. The electrical conductivity of ZnO was significantly improved, and the thermal conductivity was reduced. The mechanical properties of the composites were also enhanced. This work provides a valuable reference for dispersing nano-phases in thermoelectric materials to enhance both thermoelectric and mechanical properties.
