  text: There is a need for the development of lead-free thermoelectric materials
    for medium-/high-temperature applications. Here, we report a thiol-free tin telluride
    (SnTe) precursor that can be thermally decomposed to produce SnTe crystals with
    sizes ranging from tens to several hundreds of nanometers. We further engineer
    SnTe–Cu2SnTe3 nanocomposites with a homogeneous phase distribution by decomposing
    the liquid SnTe precursor containing a dispersion of Cu1.5Te colloidal nanoparticles.
    The presence of Cu within the SnTe and the segregated semimetallic Cu2SnTe3 phase
    effectively improves the electrical conductivity of SnTe while simultaneously
    reducing the lattice thermal conductivity without compromising the Seebeck coefficient.
    Overall, power factors up to 3.63 mW m–1 K–2 and thermoelectric figures of merit
    up to 1.04 are obtained at 823 K, which represent a 167% enhancement compared
    with pristine SnTe.
