英文摘要	An efficient technique to fabricate BiCuSeO oxyselenides thermoelectric bulks is studied. Pb doped p-type BiCuSeO ingots are synthesized by microwave processing for 4 minutes and the bulk materials with 8.7 similar to 8.9 gcm(-3) density are produced after spark plasma sintering for 5 minutes. The XRD and XPS detection results show that all the samples have nearly a single phase indexed to tetragonal BiCuSeO, and the peak positions of Pb 4f(7/2) and 4f(5/2) simple spin-orbit doublet peaks in Bi0.98Pb0.02CuSeO and Bi0.90Pb0.10CuSeO respectively are 137.93 and 142.76 eV, and 137.49 and 142.49 eV. Holes are the majority carriers with concentrations of 3.22 10(20) cm(-3) similar to 2.40 10(21) cm(-3) in the doped samples. Bi0.98Pb0.02CuSeO shows the highest ZT of 0.76 at 773 K and possible larger values can be achieved at a higher temperature. The fabricate technique described here showing great prospect in the research and manufacturing of thermoelectric bulks. (C) 2021 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
