Significantly Enhanced Thermoelectric Performance of -Type MgSb via Zn Substitution on Mg(2) Site: Optimization of Hole Concentration Through Ag Doping.

-Type MgSb-based thermoelectric materials have recently garnered significant interest due to their superior thermoelectric efficiency. Yet, the advancement of -type MgSb for thermoelectric applications is impeded by its lower dimensionless figure of merit (). In this study, we demonstrate the improved thermoelectric performance of -type MgSb through the strategic optimization of Zn content and Ag doping on the Mg/Zn(2) site.

Aqueous-Solution Synthesized p-Type CuSeTeI/CuO Composite and Thermoelectric Performance of TEG Made of 6 Pairs of p-Leg CuSeTeI/CuO Composite and n-Leg InSbBi.

CuSe-based thermoelectric materials exhibit high dimensionless figure of merit () values at elevated temperatures (900-1000 K) but relatively lower values at intermediate temperatures, approximately 500 K. We synthesized a series of polycrystalline CuSeTeI/CuO composites (where = 0.00, 0.

Enhanced Thermoelectric Performance of -Type MgZnSb/Sb Composites: The Role of ZnSb/Sb Composites.

MgSb-based Zintl compounds have garnered recent attention as promising materials for thermoelectric applications due to their low thermal conductivity and high values as n-type materials. However, the values of -type materials are lower compared to their -type counterparts. Through a straightforward process involving cold pressing and evacuating-and-encapsulating sintering, we have successfully synthesized a variety of -type MgZnSb/Sb composites by adding the ZnSb-4%Sb composite into the MgSb host material.
