Salman_2021, title={SYNTHESIS OF FILLED SKUTTERUDITE COMPOUND YBXCO4SB12 BY SOLID STATE MICROWAVE}, volume={18}, url={https://archives.palarch.nl/index.php/jae/article/view/8951}, abstractNote={<p>The skutterudite semiconductor thermoelectric alloy Yb<sub>x</sub>Co<sub>4</sub>Sb<sub>12</sub> (<em>x = 0.15</em>- 0.3) was synthesized by solid-state microwave. The morphology of the micro/nanostructure and polycrystalline stoichiometric ratio of Yb<sub>x</sub>Co<sub>4</sub>Sb<sub>12</sub> (<em>x =0.15</em>- 0.3) were examined using scanning electron microcopy (SEM) and energy dispersive X-ray spectra (EDX). The structures of the skutterudite polycrystalline alloy Yb<sub>x</sub>Co<sub>4</sub>Sb<sub>12</sub> were examined by X-ray diffraction (XRD) patterns. A cubic structure was observed, and the lattice constant increased with increasing amount of Yb, with doping levels from <em>x</em>=0.15 to 0.3 and saturated with increments. The thermoelectric properties including electrical conductivity (<em>σ</em>), Seebeck coefficient (<em>α</em>) and electrical power factor)PF) were measured at a temperature range of 298–700 K. The transport properties of skutterudites alloy demonstrate a semiconductor behavior, during the temperature measurement, which indicated the change of electronic band structure. The Hall effect and Seebeck coefficient measurements have shown p-type conductivity in samples. The highest value of the Seebeck coefficient was 176.84 μV/K with doping levels <em>x</em>=0.3, at 329 K.</p> <p>Keywords: Skutterudite semiconductor, Yb<sub>x</sub>Co<sub>4</sub>Sb<sub>12</sub>, thermoelectric materials, thermoelectric properties, X-ray diffraction.</p>}, number={08}, journal={PalArch’s Journal of Archaeology of Egypt / Egyptology}, author={Hussein Ghafel AL-Toki, M.
