"Enhanced thermoelectric figure of merit in p-type DDy(Fe1-xCox)4Sb12";
Solid State Phenomena,
Thermoelectric (TE) properties of skutterudites DDy(Fe1-xCox)4Sb12 for 0.2 x 0.3 were studied in the temperature range from 300 K to 800 K and compared with values for x = 0. Didymium (DD, 4.76 mass % Pr and 95.24 mass % Nd) was used as natural double filler. At Co-concentrations 0.225 x 0.25 maximum TE-performance was obtained with impressive power-factors (4.5 mW/mK2) and ZTs (ZT1.2 at 700 K). Furthermore these skutterudites maintain the high ZT over a broad temperature range providing an excellent p-leg for high-efficiency thermoelectric power generation.
