Abstract
In this study, polycrystalline samples of the compounds PbSnS2 and PbSnS1.94Cl0.06 were investigated. These samples were obtained by liquid-phase synthesis, followed by mechanical grinding and consolidation by spark plasma sintering. It was found that the substitution of sulfur positions with chlorine resulted in a significant increase in the mobility of charge carriers, from 9.54 to 931.12 cm2⋅V−1⋅s−1, at 415 K. Furthermore, the power factor at 750 K was determined to be 0.25 mW⋅m−1⋅K−2 for the PbSnS1.94Cl0.06 sample. A comparative analysis of the electro-transport properties of single- and polycrystalline samples was conducted, thereby revealing the predominant role of the scattering of charge carriers at grain boundaries and defects in the latter.
