How Severe Plastic Deformation Changes the Mechanical Properties of Thermoelectric Skutterudites and Half Heusler Alloys

Autor: Gerda Rogl, Peter F. Rogl

Publikováno v: Frontiers in Materials, Vol 7 (2020)

Thermoelectric leg materials with a high figure of merit, ZT, are the essential basis to build thermoelectric generators, directly converting waste heat into electricity. Skutterudites and half-Heusler alloys are promising candidates because they can

Simultaneous optimization of power factor and thermal conductivity via Te and Se double substitution in Cu12Sb4S13 tetrahedrite

Autor: Sahil Tippireddy, Padaikathan Pambannan, Peter Rogl, Ramesh Chandra Mallik, Gerda Rogl, Katharina Werbach, Umasankar Rout

Publikováno v: Scripta Materialia. 188:151-156

The present study reports the structural, electronic, elastic, and thermoelectric properties of Cu12Sb3.9Te0.1S13-xSex (x = 0, 0.1, 0.5, 0.75 and 1) tetrahedrite. The thermal conductivity was reduced due to charge carrier compensation (by Te), weaken

Half-Heusler alloys: Enhancement of ZT after severe plastic deformation (ultra-low thermal conductivity)

Autor: Jiri Bursik, Ernst Bauer, Ramesh Chandra Mallik, Xing-Qiu Chen, Michael J. Zehetbauer, Michael Kerber, Peter Rogl, Lei Wang, Sanyukta Ghosh, Andriy Grytsiv, Gerda Rogl

Publikováno v: Acta Materialia. 183:285-300

Several n- and p-type Half-Heusler (HH) thermoelectric materials (Ti0.5Zr0.5NiSn-based and NbFeSb-based) have been processed by high-pressure torsion (HPT) to improve their thermoelectric performance via a drastic reduction towards ultra-low thermal
