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...

متن کاملResonant Oscillations in Multiple-Filled Skutterudites
Partially filled skutterudites were investigated by ultrafast spectroscopy using a femtosecond laser system, which excites resonant oscillations due to the host–guest interactions. To investigate the effect of individual guest elements on phonon-mediated thermal transport, four skutterudite samples were studied: three samples partially filled with Ba, Yb, and La, respectively, and a fourth with...
متن کاملUltrafast carriers dynamics in filled-skutterudites
Carrier dynamics of filled-skutterudites, an important class of thermoelectric materials, is investigated using ultrafast optical spectroscopy. By tuning the wavelength of the probe laser, charge transfers at different electronic energy levels are interrogated. Analysis based on the KramersKronig relation explains the complex spectroscopy data, which is mainly due to band filling caused by phot...
