Thermoelectric and Transport Properties of n-type Palladium - Doped Chalcopyrite Cu1-xPdxFeS2 Compounds
Original language description
Semiconducting CuFeS2 with a diamond-like structure has been recently studied as a potential candidate for thermoelectric applications. In the present study, Pd substitution for Cu was examined in terms of thermoelectric properties. A series of Pd-doped Cu1-xPdxFeS2 (x=0-0.1) samples were synthesized. The thermoelectric and transport properties of hot-pressed sample pellets were characterized. We observed three effects: (1) Pd substituted for Cu behaves as an effective donor, increasing the free electron concentration. (2) Formation of the foreign phasePdSwas observed above the solubility limit of Pd in CuFeS2 (x 0.02). (3) Segregation of the foreign phase is accompanied by the formation of FeCu2+ antisite defects. All these effects synergically enhanced both the power factor S-2 sigma and the thermoelectric parameter ZT. The highest values of the power factor (approximate to 1mWm(-1)K(-1)) and the ZT parameter (approximate to 0.19 at 573K) were achieved in the Cu0.9Pd0.1FeS2 sample.
