Abstract

The¹²¹ Sb partial density of phonon states (DPS) in nanopowder antimonides were obtained with nuclear inelastic scattering on Zn1+xSb, FeSb2, and NiSb prepared by a wet chemistry route. The DPS is compared with the bulk counterpart. An increase of the Debye level indicative of a decrease of the isothermal speed of sound is systematically observed. This observation reveals that the decrease in speed of sound observed in nanostructured thermoelectric materials is not restricted to sintered nanocomposites.
