Gram-Scale Synthesis of Tetrahedrite Nanoparticles and Their Thermoelectric Properties.

Here, we report a method for facile gram-scale synthesis of tetrahedrite (CuSbS) nanoparticles (NPs) with high quality and good reproducibility. The obtained NPs had a well-defined tetrahedral shape with a mean edge length of ∼70 nm. We sintered the NPs by the hot press technique to fabricate a nanostructured pellet for thermoelectric measurements.
