Abstract
In this study, half-Heusler (HH) thermoelectric materials Nb 0.8Hf 0.2FeSb 0.98Sn 0.02 (p-type) and Hf 0.25Zr 0.25Ti 0.5NiSn 0.98Sb 0.02 (n-type) were synthesized using induction melting and spark plasma sintering. For alloying, a conventional induction melting technique was employed rather than arc melting, for mass production compatibility, and the thermoelectric properties of the materials were analyzed. The maximum dimensionless..... More

Abstract
Development new high-performance thermoelectric materials for more efficient power generation systems and eco-friendly refrigerating systems has been challenging. Over the past few decades, thermoelectric studies have been focused on increasing the thermoelectric properties of materials. However, for conventional applications, developing of thermoelectric devices or modules with lower cost and..... More
