Subsequent measurements were carried out in the temperature range from 20 to 270°C, and for compositions from pure Bi2Te3 to xAg2Te = 0.65 selected along the pseudo-binary section of Ag-Bi-Te ternary system. It was found that conductivity vs. temperature dependence shows visible jump between 140 and 150°C in samples with highest Ag2Te content, which is due to monoclinic => cubic Ag2Te phase transformation. Measured Seebeck coefficient is negative for all samples indicating they are n-type semiconductors. Evaluated power factor is of the order 1.52·10–3 and it decreases with increasing Ag2Te content (at. %). Recalculated thermal conductivity is of the order of unity in W/(m K), and is decreasing with Ag2Te addition. Finally, evaluated Figure of Merit is 0.43 at 100°C and decreases with temperature rise.}, type={Article}, title={The Influence of Ag2Te Addition on Thermoelectric Properties of Bismuth Telluride}, URL={http://journals.pan.pl/Content/122499/PDF/AMM-2022-1-01-Drzewowska.pdf}, doi={10.24425/amm.2022.137466}, keywords={thermoelectric materials, Seebeck coefficient, resistivity, thermal diffusivity, Bi2Te3-Ag2Te system}, }
