Tuning the Eu valence in EuPd_3B_x: pressure versus valence electron count - a combined computational and experimental study
M. Schmitt, R. Gumeniuk, A. Trapananti +8
In a joint theoretical and experimental study we investigate the pressure dependence of the Eu valence in EuPd_3B_x (0 <= x <= 1). Density functional band structure calculations ar…
Nanostructuring of Ba8Ga16Ge30 clathrates
Vicente Pachecoa, Raul Cardoso--Gil, Deepa Kasinathan +6
First thermoelectric properties measurements on bulk nanostructured Ba8Ga16Ge30 clathrate-I are presented. A sol-gel-calcination route was developed for preparing amorphous nanosiz…
Symmetry preserving lattice collapse in tetragonal SrFe_(2-x)Ru_xAs_2 (x = 0, 0.2) -- a combined experimental and theoretical study
Deepa Kasinathan, Miriam Schmitt, Klaus Koepernik +8
In a joint experimental and theoretical study, we investigate the isostructural collapse from the ambient pressure tetragonal phase to a collapsed tetragonal phase for non-supercon…
Synthesis and thermoelectric characterization of Bi2Te3 nanoparticles
Marcus Scheele, Niels Oeschler, Katrin Meier +3
We report a novel synthesis for near monodisperse, sub-10-nm Bi2Te3 nanoparticles. At first, a new reduction route to bismuth nanoparticles is described which are applied as starti…
