Science of Advanced Materials, 3 (2011), 517 - 538.

The present article provides a comprehensive compilation and discussion of mechanical properties of unfilled and filled skutterudites, covering thermal expansion, Vickers hardness, the various elastic moduli and fracture toughness, as a function of temperature, composition, density (porosity) and filling level. Differences of thermoelectric properties for p-type and n-type materials as well as between micro- and nano-structured alloys are discussed. Wherever available, experimental data are compared with those from DFT model simulations. As Debye and Einstein temperatures are of importance to define the vibrational spectra of thermoelectric materials, corresponding values extracted from various measurement techniques such as thermal expansion, sound velocity, specific heat, resistivity or X-ray measurements are evaluated.
