High-performance n-type YbxCo4Sb12: from partially filled skutterudites towards composite thermoelectrics

The filling fraction limit (FFL) of skutterudites, that is, the complex balance of formation enthalpies among different species, is an intricate but crucial parameter for achieving high thermoelectric performance. In this work, we synthesized a series of YbxCo4Sb12 samples with x=0.2–0.6 and systemically studied the FFL of Yb, which is still debated even though this system has been extensively ...

Dynamics of coherent acoustic phonons in thin films of CoSb3 and partially filled YbxCo4Sb12 skutterudites

Skutterudites are considered as interesting material for thermoelectric applications. Filling foreign atoms into the cagelike structure of a CoSb3 skutterudite is beneficial to its thermoelectric properties by increasing phonon scattering while maintaining the electrical conductivity. In this paper we demonstrate the generation and detection of coherent acoustic phonons in thin films of CoSb3 a...

Coupled Vibration of Partially Fluid-Filled Laminated Composite Cylindrical Shells

In this study, the free vibration of partially fluid-filled laminated composite circular cylindrical shell with arbitrary boundary conditions has been investigated by using Rayleigh-Ritz method. The analysis has been carried out with strain-displacement relations based on Love’s thin shell theory and the contained fluid is assumed irrotational, incompressible and inviscid. After determining the...

Optical properties of MFe4P12 filled skutterudites

Infrared reflectance spectroscopy measurements were made on four members of the MFe4P12 family of filled skutterudites, with M5La, Th, Ce, and U. In progressing from M5La to U the system undergoes a metalinsulator transition. It is shown that, although the filling atom induces such dramatic changes in the transport properties of the system, it has only a small effect on lattice dynamics. We dis...
