英文摘要	A series of Se- and Te-doped skutterudite Co4Sb11.9-xTexSe0.1 (x = 0.2, 0.3, 0.4, 0.5, 0.6) samples are prepared by a process encompassing rapid microwave synthesis for 5 min and spark plasma sintering for 5 min and their microstructure and thermoelectric properties are studied. Nearly single-phase Co4Sb11.9-xTexSe0.1 ingots are produced by the microwave synthesis and matrix grains appear after the microwave treatment. The influence of the dopant concentration on the thermoelectric properties is discussed. The largest dimensionless thermoelectric figure of merit of 0.81 is observed from Co4Sb11.5Te0.4Se0.1 at 773 K in addition to a thermal conductivity of 2.8 Wm−1K−1. The preparation technique presented here has many advantages compared to conventional methods especially the efficiency. © 2019 Elsevier B.V.
