593 Thermoelectric Performance of Sn and Bi Double-Doped Permingeatite
Hee-Jae Ahn, Il-Ho Kim
Korean J. Met. Mater. 2022;60(8):593-600.   Published online 2022 Jul 12
DOI: https://doi.org/10.3365/KJMM.2022.60.8.593

Abstract
In this study, mechanical alloying was performed to synthesize permingeatite Cu3Sb1-x-ySnxBiySe4 (0.02 ≤ x ≤ 0.06 and 0.02 ≤ y ≤ 0.04) doped with Sn and Bi. Hot pressing was subsequently conducted to achieve dense sintered bodies. When the Bi content was constant, the carrier concentration increased with the Sn..... More

724 Charge Transport and Thermoelectric Properties of Sn-Doped Tetrahedrites Cu12Sb4-ySnyS13
Hee-Jae Ahn, Il-Ho Kim
Korean J. Met. Mater. 2021;59(10):724-731.   Published online 2021 Sep 6
DOI: https://doi.org/10.3365/KJMM.2021.59.10.724

Abstract
In this study, tetrahedrite compounds doped with Sn were prepared by mechanical alloying and hot pressing, and their charge transport and thermoelectric properties were analyzed. X-ray diffraction analysis revealed that both the synthetic powders and sintered bodies were synthesized as a single tetrahedrite phase without secondary phases. Densely sintered specimens..... More
