We report the synthesis and thermoelectric transport properties of As-doped layered pnictogen oxyselenides NdO<sub>0.8</sub>F<sub>0.2</sub>Sb<sub>1-<i>x</i></sub>As<i><sub>x</sub></i>Se<sub>2</sub> (<i>x</i> ≤ 0.6), which are predicted to show high-performance thermoelectric properties based on first-principles calculation. The crystal structure of these compounds belongs to the tetragonal <i>P</i>4/<i>nmm</i> space group (No. 129) at room temperature. The lattice parameter <i>c</i> decreases wi ...[more]
