Thermoelectric Properties of Cu1.98Se Prepared by Melt-spinning Process
용융방사법으로 제작된 Cu1.98Se의 열전특성
Jang-Yeul Tak, Young Soo Lim
탁장렬, 임영수
Korean J. Met. Mater. 2018;56(7):532-537.   Published online 2018 Jul 5
DOI: https://doi.org/10.3365/KJMM.2018.56.7.532

Abstract
Cu2Se exhibits very low thermal conductivity and the origin is known to be the "liquid-like" behavior of Cu ions around the sub-lattice of Se. Due to its very high ZT, research interest in the thermoelectric properties of this material has been increasing rapidly. However, most studies have used a conventional melting..... More

Thermoelectric Properties of Partially Double-filled (Ce1-zNdz)yFe4-xCoxSb12 Skutterudites
Ye-Eun Cha, Il-Ho Kim
Korean J. Met. Mater. 2018;56(6):465-471.   Published online 2018 Jun 4
DOI: https://doi.org/10.3365/KJMM.2018.56.6.465

Abstract
(Ce1-zNdz)yFe4-xCoxSb12 skutterudites were prepared by encapsulated melting, annealing, and hot pressing. The formation of a marcasite phase (FeSb2) was significantly suppressed by partially filling the voids with Ce/Nd and making a Co substitution at the Fe site. Both the Hall and the Seebeck coefficient values were positive, indicating that all..... More

Effects of Interface Control Using Reduced Graphene Oxide (RGO) on the Thermoelectric Transport Properties of Polycrystalline SnSe Compounds
환원 산화 그래핀을 이용한 계면제어가 다결정 SnSe의 열전 수송특성에 미치는 효과
Sang Tae Lee, Young Soo Lim
이상태, 임영수
Korean J. Met. Mater. 2018;56(2):163-169.   Published online 2018 Feb 5
DOI: https://doi.org/10.3365/KJMM.2018.56.2.163

Abstract
We report the effects of interface control using reduced graphene oxide (RGO) on the thermoelectric transport properties of polycrystalline SnSe compounds. Polycrystalline SnSe-RGO composites were prepared by the consolidation of SnSe powder coated with the RGO by hot pressing, and the RGO content was controlled to be 0, 0.2, 0.5..... More

    
Charge Transport and Thermoelectric Properties of P-type Bi2-xSbxTe3 Prepared by Mechanical Alloying and Hot Pressing
Kyung-Wook Jang, Hyeok-Jin Kim, Woo-Jin Jung, Il-Ho Kim
Korean J. Met. Mater. 2018;56(1):66-71.   Published online 2018 Jan 1
DOI: https://doi.org/10.3365/KJMM.2018.56.1.66

Abstract
Bi2-xSbxTe3 (x = 1.4–1.7) solid solutions were synthesized by mechanical alloying (MA) and consolidated by hot pressing (HP), and their charge transport and thermoelectric properties were examined. The relative densities of the hot-pressed specimens were higher than 96% on average. As the Sb content was increased, the lattice constants decreased,..... More

Effects of Sb on the Charge Transport and Power Factor of Bi2-xSbxTe3 Thermoelectric Compounds Prepared by Hot Pressing
열간 압축 방법으로 제작된 Bi2-xSbxTe3 열전소재 복합체에서 Sb 함량이 전하수송과 출력인자에 미치는 효과
Young Soo Lim, Soonil Lee
임영수, 이순일
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.....

Fabrication and Characterization of Ge2Sb2Te5 Nanowire Arrays and PEDOT: PSS Hybrid Thermoelectric Composites
Ge2Sb2Te5 nanowire arrays와 PEDOT: PSS를 이용한 유・무기 열전 복합소재 합성 및 특성평가
Sang-Hyun Roh, Jiwon Kim, Woon-Ik Park, Yang-Do Kim, Jae-Hong Lim
노상현, 김지원, 박운익, 김양도, 임재홍
Korean J. Met. Mater. 2017;55(6):432-439.   Published online 2017 Jun 1
DOI: https://doi.org/10.3365/KJMM.2017.55.6.432

Abstract
Hybrid organic/inorganic composites have recently been investigated in the thermoelectric field in an effort to interdependently manipulate the charge carriers, which are interconnected with electrical and thermal transport. The decoupling of a charge carrier’s roles in the hybrid structures can result in enhanced thermoelectric performance, by only exploiting the high..... More

Effects of Cu-doping on the Power Factor of Bi0.42Sb1.58Te3 Thermoelectric Compounds Prepared by Hot Pressing
열간 압축 방법으로 제작된 Bi0.42Sb1.58Te3 열전소재 복합체에서 Cu 도핑이 출력인자에 미치는 효과에 대한 연구
Young Soo Lim, Minseok Song, Soonil Lee, Won-Seon Seo
임영수, 송민석, 이순일, 서원선
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
