A long-standing limitation of first-principles calculations of substitutional alloy phase
diagrams is the difficulty in accounting for lattice vibrations. A survey of the theoretical and …

There has been substantial renewed interest in negative thermal expansion following the
discovery that cubic ZrW 2 O 8 contracts over a temperature range in excess of 1000 K …

As half-Heusler compounds are promising candidates for environmentally friendly and low-
cost thermoelectric materials, not only a high figure of merit and efficiency are necessary but …

A re-investigation of phase equilibria, crystal structure and homogeneity region of the Half-
Heusler (HH) phase in the ternary system Nb-Fe-Sb at 600° C has solved controversies in …

Time-of-flight and resonant ultrasound spectroscopy techniques were employed for elastic
moduli measurements on a set of various Fe4Sb12-and Co4Sb12-based skutterudites filled …

The influence of double, triple and multi-filling of didymium, Ca, Ba, Sr and Yb in
Fe3CoSb12 on the thermoelectric performance was investigated. Ball-milling followed by …

The current paper gives an overview of the newly obtained thermal expansion coefficients of
skutterudites as well as those so far available in literature. Thermal expansion was …

Materials exhibiting electronic inhomogeneities at the nanometer scale have enormous
potential for applications. Magnetic polarons are one such type of inhomogeneity which link …

N-type skutterudite Sr0. 07Ba0. 07Yb0. 07Co4Sb12 with ZT= 1.4 at 800K was processed by
high pressure torsion (HPT), a technique of severe plastic deformation (SPD) to produce a …

The best p-type skutterudites with ZT> 1.1 so far are didymium (DD) filled, Fe/Co substituted,
Sb-based skutterudites. DD0. 68Fe3CoSb12 was prepared using an annealing–reacting …
