842 Thermoelectric Transport Properties of Sb-doped SnSe2 Polycrystalline Alloys
Seung Min Kang, Jong Wook Rho, Hyungyu Cho, Sanghyun Park, Joontae Park, Sang-il Kim
Korean J. Met. Mater. 2023;61(11):842-848.   Published online 2023 Oct 29
DOI: https://doi.org/10.3365/KJMM.2023.61.11.842

Abstract
SnSe2 alloys have been investigated in recent times as potential n-type thermoelectric materials. In this study, the thermoelectric transport properties of a series of Sb-doped SnSe2, Sn(Se1-xSbx)2 (x = 0, 0.015, 0.03, 0.045, 0.06) alloys are investigated. The electrical conductivity was generally enhanced with Sb doping owing to a large..... More

431 Enhanced Thermoelectric Transport Properties in Cu-added Bi2Se3 Polycrystalline Alloys
Hyungyu Cho, TaeWan Kim, Seung Min Kang, Sanghyun Park, Sang-il Kim
Korean J. Met. Mater. 2023;61(6):431-436.   Published online 2023 May 18
DOI: https://doi.org/10.3365/KJMM.2023.61.6.431

Abstract
The addition of Cu to layered Bi2Te3-based thermoelectric alloys has been studied as an effective way to enhance thermoelectric transport properties. In this study, the influence of adding Cu to Bi2Se3 alloys, which have the same rhombohedral crystal structure as Bi2Te3, was investigated by synthesizing a series of CuxBi2Se3 (x..... More
