  text: Methodologies that involve the use of nanoparticles as “artificial atoms”
    to rationally build materials in a bottom-up fashion are particularly well-suited
    to control the matter at the nanoscale. Colloidal synthetic routes allow for an
    exquisite control over such “artificial atoms” in terms of size, shape, and crystal
    phase as well as core and surface compositions. We present here a bottom-up approach
    to produce Pb–Ag–K–S–Te nanocomposites, which is a highly promising system for
    thermoelectric energy conversion. First, we developed a high-yield and scalable
    colloidal synthesis route to uniform lead sulfide (PbS) nanorods, whose tips are
    made of silver sulfide (Ag2S). We then took advantage of the large surface-to-volume
    ratio to introduce a p-type dopant (K) by replacing native organic ligands with
    K2Te. Upon thermal consolidation, K2Te-surface modified PbS–Ag2S nanorods yield
    p-type doped nanocomposites with PbTe and PbS as major phases and Ag2S and Ag2Te
    as embedded nanoinclusions. Thermoelectric characterization of such consolidated
    nanosolids showed a high thermoelectric figure-of-merit of 1 at 620 K.
