  text: Pb, Te, Ag and Se, when reacted in a 1:1:x:1 (x = 1.9, 2.0, 2.01) molar ratio,
    form a two phase composite which consists of a phase which crystallizes in the
    fcc cubic PbSe structure and a phase that crystallizes in the Ag2Te structure.
    In this article, we demonstrate that by varying the Ag concentration, we can manipulate
    which variant of the Ag2Te structure stabilizes at room temperature (monoclinic
    α-Ag2Te or cubic β-Ag1.9Te) and can consequently manipulate the electrical and
    thermal transport behavior of the composite and hence the thermoelectric performance.
    Additionally, we show that Cu-doping results in an overall improvement in thermoelectric
    performance. Our results suggest that formation of composites is a viable path
    for achieving a phonon-glass-electron-crystal (PGEC) alloy.
