biostudies-literatureUnknown13(12)Park OSome transition-metal dichalcogenides have been actively studied recently owing to their potential for use as thermoelectric materials due to their superior electronic transport properties. Iron-based chalcogenides, FeTe₂, FeSe₂ and FeS₂, are narrow bandgap (~1 eV) semiconductors that could be considered as cost-effective thermoelectric materials. Herein, the thermoelectric and electrical transport properties FeSe₂-FeS₂ system are investigated. A series of polycrystalline samples of the nominal composition of FeSe_2-<i>x</i>S<i>_x</i> (<i>x</i> = 0, 0.2, 0.4, 0.6, and 0.8) samples are synthesized by a conventional solid-state reaction. A single orthorhombic phase of FeSe₂ is successfully synthesized for <Micromachines2066https://www.ebi.ac.uk/biostudies/studies/S-EPMC9784414biostudies-literaturePhase Formation Behavior and Thermoelectric Transport Properties of S-Doped FeSe_2-<i>x</i>S<i>_x</i> Polycrystalline Alloys.PMC9784414Kim SILee SWPark OPark SJfalsePhase Formation Behavior and Thermoelectric Transport Properties of S-Doped FeSe_2-<i>x</i>S<i>_x</i> Polycrystalline Alloys.Some transition-metal dichalcogenides have been actively studied recently owing to their potential for use as thermoelectric materials due to their superior electronic transport properties.
