New discovery by Poudeu team could pave way to improved thermoelectric materials

MSE is pleased to report that Associate Professor Pierre Ferdinand P. Poudeu's manuscript "Coherent Magnetic Nanoinclusions Induce Charge Localization in Half-Heusler Alloys Leading to High-Tc Ferromagnetism and Enhanced Thermoelectric Performance" was recently published in the prestigious Royal Society of Chemistry's Journal of Materials Chemistry A  IF: 9.9 

"This paper introduces a new concept for further enhancement in the thermoelectric performance of current leading thermoelectric materials," Poudeu said. "Our paper demonstrates that the incorporation of magnetic inclusions within a semiconducting matrix leads to the reduction in the effective density of free chargecarriers and thermal conductivity, but increases incharge carrier mobility and thermopower, which results in a large increase in the thermoelectric figure of merit.” 

This new approach, he added, is complementary to strategies currently used to enhance the performance of thermoelectric materials and therefore could enable additional improvements in the performance on current leading thermoelectric materials.

The first author on this manuscript is Ruiming Lu, a fourth-year MSE Ph.D. student. Other MSE contributing authors include Ph.D. student Juan Lopez and Yuanfeng Liu (PHD '15).
