  text: The bottom-up assembly of colloidal nanocrystals is a versatile methodology
    to produce composite nanomaterials with precisely tuned electronic properties.
    Beyond the synthetic control over crystal domain size, shape, crystal phase, and
    composition, solution-processed nanocrystals allow exquisite surface engineering.
    This provides additional means to modulate the nanomaterial characteristics and
    particularly its electronic transport properties. For instance, inorganic surface
    ligands can be used to tune the type and concentration of majority carriers or
    to modify the electronic band structure. Herein, we report the thermoelectric
    properties of SnTe nanocomposites obtained from the consolidation of surface-engineered
    SnTe nanocrystals into macroscopic pellets. A CdSe-based ligand is selected to
    (i) converge the light and heavy bands through partial Cd alloying and (ii) generate
    CdSe nanoinclusions as a secondary phase within the SnTe matrix, thereby reducing
    the thermal conductivity. These SnTe-CdSe nanocomposites possess thermoelectric
    figures of merit of up to 1.3 at 850 K, which is, to the best of our knowledge,
    the highest thermoelectric figure of merit reported for solution-processed SnTe.
