## Description

- description: "We report on a study of bulk SiGe-MnTe composites obtained via spark
    plasma sintering of mixed powders\r\ncomposed of SiGe that was fabricated by mechanical
    alloying and MnTe prepared via solid-state reaction. The presence of MnTe in the
    SiGe matrix led to an increase in the electrical conductivity by ~ 50 % and a
    decrease in the lattice thermal conductivity of the samples by ~ 28 %, while the
    Seebeck coefficient was reduced from 252 μV K-1 to 197 μV K-1 at 1000 K. As a
    result, the peak zT of 0.75 was obtained for pristine Si80Ge20B2, and 0.8 for
    Si80Ge20B2 + 4 wt% MnTe at 1000 K."
