Uniformity of Thermoelectric Properties of N-type Bi<sub>2</sub>Te<sub>3-y</sub>Se<sub>y</sub> Bulky Compacts
Se-Hyeon Choi, Go-Eun Lee, Il-Ho Kim
Korean J. Met. Mater. 2024;62(5):385-392.   Published online 2024 May 5
DOI: https://doi.org/10.3365/KJMM.2024.62.5.385

Abstract
Because n-type Bi2Te3-based materials exhibit lower thermoelectric performance than p-type materials and because their thermoelectric properties are sensitively changed by the composition and carrier concentration, optimizing these aspects in n-type materials is necessary to improve the thermoelectric figure of merit (ZT). In this study, the thermoelectric performance of n-type Bi2Te3-based..... More

Enhanced Thermoelectric Transport Properties of <i>n</i>-type InSe by Sn doping
Sung-sil Choo, Seok-won Hong, Hyun-Sik Kim, Sang-il Kim
Korean J. Met. Mater. 2020;58(5):348-352.   Published online 2020 Apr 20
DOI: https://doi.org/10.3365/KJMM.2020.58.5.348

Abstract
Layered post transition metal chalcogenides such as SnSe, SnSe2, In2Se3, and In4Se3 have attracted attention as promising thermoelectric materials due to their intrinsically low lattice thermal conductivities. Recently, n-type indium selenide (InSe) based materials have also been suggested as good candidates for thermoelectric materials by optimizing their electrical properties, i.e.,..... More
