n-Type Mg3Sb2-based thermoelectric materials have recently garnered significant interest due to their superior efficiency. Yet, the advancement of p-type Mg3Sb2 for applications is impeded by its lower dimensionless figure merit (zT). In this study, we demonstrate improved performance through strategic optimization Zn content and Ag doping on Mg/Zn(2) site. Initially, samples Mg3-xZnxSb2 (x = 0, 0.5, 1.0, 1.5) were synthesized via elemental reactions within a Pyrex tube, followed...
Materials including Cu 2 Se, Se 0.96− x S Te 0.04 ( = 0.00–0.03) and 2− y 0.94 0.02 0.00–0.04) were synthesized using aqueous solution processing at room temperature cold-press sintered under vacuum 650 °C for 6 hours.
Mg3Sb2-based Zintl compounds have garnered recent attention as promising materials for thermoelectric applications due to their low thermal conductivity and high zT values n-type materials. However, the of p-type are lower compared counterparts. Through a straightforward process involving cold pressing evacuating-and-encapsulating sintering, we successfully synthesized variety Mg3–xZnxSb2/Sb composites by adding ZnSb-4%Sb composite into Mg3Sb2 host material. Structural analyses provided...
