Abstract:
Polycrystalline Cu(1.8)S compounds were fabricated by using a combined process of mechanical alloying and spark plasma sintering. The Cu(1.8)S sample with a second Cu(1.96)S phase and a lot of micro pores shows its maximum ZT value 0.5 at 673 K which is the highest value for p-type sulfide thermoelectric materials so far.
