Enhanced Thermoelectric Performance of Sn-Doped Permingeatites Cu<sub>3</sub>Sb<sub>1-y</sub>Sn<sub>y</sub>Se<sub>4</sub>
Ji-Hee Pi, Go-Eun Lee, Il-Ho Kim
Korean J. Met. Mater. 2023;61(1):46-53.   Published online 2022 Dec 28
DOI: https://doi.org/10.3365/KJMM.2023.61.1.46

Abstract
In this study, Cu3Sb1-ySnySe4 (0 ≤ y ≤ 0.08) permingeatites were synthesized via mechanical alloying followed by hot pressing. The phase transformation, microstructure, charge transport parameters of the permingeatites, and their thermoelectric properties were analyzed. The permingeatites were present in a single phase with a tetragonal structure, and secondary phases..... More

                
Effects of Ge Doping on the Charge Transport and Thermoelectric Properties of Permingeatites Cu<sub>3</sub>Sb<sub>1y</sub>Ge<sub>y</sub>Se<sub>4</sub>
Ji-Hee Pi, Go-Eun Lee,, Il-Ho Kim
Korean J. Met. Mater. 2021;59(6):422-429.   Published online 2021 May 26
DOI: https://doi.org/10.3365/KJMM.2021.59.6.422

Abstract
Permingeatites Cu3Sb1−yGeySe4 (0 ≤ y ≤ 0.14) were synthesized by mechanical alloying and hot pressing. The charge-transport parameters (Hall coefficient, carrier concentration, mobility, and Lorenz number) and thermoelectric properties (electrical conductivity, Seebeck coefficient, power factor, thermal conductivity, and figure of merit) were examined with respect to the Ge doping level......

Charge Transport and Thermoelectric Properties of Mn-Doped Tetrahedrites Cu<sub>12-x</sub>Mn<sub>x</sub>Sb<sub>4</sub>S<sub>13</sub>
Sung-Yoon Kim, Go-Eun Lee, Il-Ho Kim
Korean J. Met. Mater. 2021;59(5):329-335.   Published online 2021 Apr 6
DOI: https://doi.org/10.3365/KJMM.2021.59.5.329

Abstract
Mn-doped tetrahedrites Cu12-xMnxSb4S13 (0.1 ≤ x ≤ 0.4) were synthesized by mechanical alloying (MA) and sintered by hot pressing (HP). A single tetrahedrite phase was synthesized by MA without post-annealing, and it was stable without any phase changes after HP. The hot-pressed specimens had a relative density higher than 98.6%...... More

Charge Transport and Thermoelectric Properties of N-type Bi<sub>2-x</sub>Sb<sub>x</sub>Te<sub>3-y</sub>Se<sub>y</sub>:I<sub>m</sub> Prepared by Encapsulated Melting and Hot Pressing
Woo-Jin Jung, Hyeok-Jin Kim, Il-Ho Kim
Korean J. Met. Mater. 2018;56(7):544-550.   Published online 2018 Jul 5
DOI: https://doi.org/10.3365/KJMM.2018.56.7.544

Abstract
Iodine-doped n-type Bi2-xSbxTe3-ySey:Im (x = 0.1–0.2, y = 0.15–0.6, and m = 0.0025–0.005) quaternary solid solutions were prepared by encapsulated melting (EM) and hot pressing (HP). The lattice constants of the resulting materials decreased with increasing Sb and Se contents, whereas the amount of I dopant was too small to..... More

Korean J. Met. Mater. 2017;55(9):651-656.   Published online 2017 Aug 30
DOI: https://doi.org/10.3365/KJMM.2017.55.9.651

Abstract
We report the effects of Sb content on the charge transport and power factor of Bi2-xSbxTe3(1.56 ≤χ≤ 1.74) compounds prepared by hot pressing. From the temperature-dependence of the electrical conductivity, it was found that the charge transport in the compounds was predominantly governed by acoustic phonon scattering, and additionally affected.....

Korean J. Met. Mater. 2017;55(6):427-431.   Published online 2017 Jun 1
DOI: https://doi.org/10.3365/KJMM.2017.55.6.427

Abstract
We report the effects of incorporated Cu on the thermoelectric transport properties of Bi0.42Sb1.58Te3 compounds prepared by the hot pressing method. The hole concentration in the compound increased significantly with the increase in the Cu content. The acceptor role of Cu was manifested by Hall measurements and also by the..... More
