The figure-of-merit of p-type half-Heusler alloys is low due to high effective charge carrier mass and concentration. To offset this decrease a composite strategy has been adopted wherein a modified HfCoSb alloy and Cu2Te based chalcogenide have been selected as two p-type components. The ...

Yan X, Liu W, Chen S, Wang H, Zhang Q, Chen G, Ren Z. Thermoelectric property study of nanostructured p-type half-heuslers (Hf, Zr, Ti) CoSb0. 8Sn0. 2. Advanced Energy Materials 2013;3:1195e200.X. Yan, W. S. Liu, S. Chen, H. Wang, Q. Zhang, G. Chen and Z. F. ...
The CoSb2O6 showed a tetragonal crystalline structure with cell parameters a?=?4.6495??, c?=?9.2763??, and a P42/mnm spatial group. The powders were analyzed by means of field emission scanning electron microscopy, finding microcubes (3D) with sizes of 10–25?μm, and microrods with ...
We report super-rapid preparation of p-type Nd x Fe3CoSb12 (x = 0.8, 0.85, 0.9, 0.95, 1.0) skutterudite compounds via a homemade induction melting assembly inside a glovebox followed by spark plasma sintering. Compared with samples prepared by solid-state reaction, the processing time ...
