Magneto-thermal conductivity effect and enhanced thermoelectric figure of merit in Ag2Te

Keisuke Hirata et al.

Summary: This study reports a large magneto-thermal conductivity effect in Ag2Te, which can be used in heat flow switches and thermoelectric devices at various temperatures, including room temperature. When a magnetic field of mu H-0 = 9 T is applied perpendicular to the heat and electric currents, the thermal conductivity of Ag2Te decreases by 61%. This effect is mainly due to the suppressed electronic thermal conductivity and magnetoresistance effect, resulting in a significant increase in the thermoelectric figure of merit.

When thermoelectric materials come across with magnetism

Chen-Chen Zhao et al.

Summary: The role of magnetism in recent advances of thermoelectric optimization is significant, providing new avenues for further enhancement. Magnetic thermoelectric materials can be treated similarly to other materials, while magnetic doping and the use of magnetic second-phase nanoclusters and external magnetic fields offer new possibilities for optimization.

Enhanced atomic ordering leads to high thermoelectric performance in AgSbTe2

Subhajit Roychowdhury et al.

Summary: By optimizing atomic disorder and cadmium doping in polycrystalline silver antimony telluride, high thermoelectric performance with near room-temperature figure of merit ZT of around 1.5 and maximum ZT of around 2.6 at 573 kelvin is achieved. This strategy of enhancing cationic ordering while reducing lattice thermal conductivity is applicable to most thermoelectric materials with inherent atomic disorder.
