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...
متن کاملEffect of partial void filling on the lattice thermal conductivity of skutterudites
Polycrystalline samples of antimonides with the skutterudite crystal structure with La partially filling the voids have been prepared in an effort to quantify the impact of partial void filling on the lattice thermal conductivity of these compounds. It is observed that a relatively small concentration of La in the voids results in a relatively large decrease in the lattice thermal conductivity....
متن کاملLattice thermal conductivity of nanoporous Si: Molecular dynamics study
Lattice thermal conductivity !l of Si with nanometer-sized pores along the #001$ direction is calculated as a function of pore diameter !dp" and pore spacing !ds" by employing a molecular dynamics approach. Our results show that !l across pores is smaller than the bulk value by over two orders of magnitude at room temperature, and that it decreases !increases" as a function of dp !ds" for fixed...
