## Description

- description: In this work, Bi1−xPbxCu1−x SeO (x = 0, 0.02, 0.06, and 0.08) compounds
    were synthesized by a solid state reaction followed by spark plasma sintering.
    The effect of simultaneous Bi to Pb substitution and Cu vacancy introduction on
    thermoelectric properties was investigated systematically. The power factor was
    significantly enhanced, contributing to the increase in the zT value. As a result,
    the zTmax of 0.75 at 773 K was obtained for the Bi0.94Pb0.06Cu0.94SeO sample.
    To reveal the factors constraining the zTmax of Bi1−xPbxCuSeO-based oxyselenides,
    a further careful analysis of literature data was performed. We highlighted that
    for Pb-doped oxyselenides, the power factor is almost independent of the synthesis
    technique, while the lattice thermal conductivity is the main property determining
    zTmax and is highly affected by the synthesis method.
