  text: In the quest for more efficient thermoelectric material able to convert thermal
    to electrical energy and vice versa, composites that combine a semiconductor host
    having a large Seebeck coefficient with metal nanodomains that provide phonon
    scattering and free charge carriers are particularly appealing. Here, we present
    our experimental results on the thermal and electrical transport properties of
    PbS-metal composites produced by a versatile particle blending procedure, and
    where the metal work function allows injecting electrons to the intrinsic PbS
    host. We compare the thermoelectric performance of composites with microcrystalline
    or nanocrystalline structures. The electrical conductivity of the microcrystalline
    host can be increased several orders of magnitude with the metal inclusion, while
    relatively high Seebeck coefficient can be simultaneously conserved. On the other
    hand, in nanostructured materials, the host crystallites are not able to sustain
    a band bending at its interface with the metal, becoming flooded with electrons.
    This translates into even higher electrical conductivities than the microcrystalline
    material, but at the expense of lower Seebeck coefficient values.
