Bulk polycrystalline chalcogenides were prepared from chalcogenide nanocrystals synthesized in high yields by a variety of chemical processes. Doping of the nanocrystals allowed for the modification of the carrier concentration in the bulk composites. Densification employing spark plasma sintering dimensionally integrated nanoscale grains within a bulk matrix, resulting in a uniform dispersion of nonconglomerated nanocrystals. Transport properties of the resulting dimensional nanocomposites were evaluated through temperature dependent resistivity, Hall, Seebeck coefficient, and thermal conductivity measurements. These properties were investigated as a function of nanocrystal size and composition. The results are discussed in terms of the potential for thermoelectric applications.
