Název v původním jazyce

Nanograined n- and p-type chalcopyrite CuFeS2 prepared by mechanochemical synthesis and sintered by SPS

Popis výsledku v původním jazyce

Chalcopyrite CuFeS2, a ternary semiconductor, is an antiferromagnet with a promising thermoelectricpotential. Since the thermoelectric efficiency of CuFeS2 is generally limited by high lattice thermal conductivity,it is highly desirable to lower the thermal conductivity without deterioration of other thermoelectric character-istics. Considering the interconnection between thermal conductivity, magnetic order and grain size in magneticceramics, we attempted to produce doped nanostructured chalcopyrite via mechanosynthesis and SPS sintering.We succeeded to prepare bothn-andp-type nanostructured ceramics. We discussed the origin of highly depressedthermal conductivity with respect to the grain size and the magnetic properties, and confirm the high technologi-cal potential of high-energy milling with respect to thermoelectric potential of CuFeS2.
