International audience; We report on a detailed investigation of the structural and transport properties of BixSb2-xTe3 (x = 0.40 and 0.48) samples, prepared by either water quenching or melt-spinning (MS) and consolidated by spark plasma sintering (

Chalcogenides are currently receiving attention due to their interesting thermoelectric properties that stem from their complex crystal structures and semiconducting properties. Here, we report on the synthesis and measurements of the transport prope

The polycrystalline In0.25Co4Sb12 n-type skutterudite was ball-milled to reduce its grain size and lattice thermal conductivity by enhanced phonon scattering at grain boundaries. To inhibit the grain size growth which occurs during the densification

In this work, we present our attempt to improve the thermoelectric performance of melt-spun (MS) Sb2−x Bi x Te3+y samples densified by spark plasma sintering (SPS) through two different methods: (1) alignment of the MS ribbons in the SPS die; (2) r
