Besides alloying, nanostructuring was implemented to improve the thermoelectric properties in Fe2VAl. This Heusler alloy indeed displays a thermoelectric figure of merit too small for applications (ZT ~ 0.1 at 300 K) which is caused by a large lattic

Y$_{0.9}$Gd$_{0.1}$Fe$_{2}$, which crystallizes in a C15 cubic structure, can absorb up to 5 H/f.u. and its pressure-composition isotherm displays a multiplateau behavior related to the existence of several hydrides with different crystal structures.

In this article, we investigate the lattice thermal conductivity in the thermoelectric Fe2VAl Heusler alloy by implementing a Green’s function approach to describe phonon-defect scattering mechanisms in the pristine and substituted compounds. Forme

High purity CoSb3, Ni0.06Co0.94Sb3 and In0.13Co4Sb12 were synthesized from oxides by magnesioreduction. This novel synthesis route to CoSb3-based skutterudites directly yields highly crystalline powders with submicronic grain size. Densified mesostru
