Ab initio molecular dynamics simulations of negative thermal expansion in ScF3: The effect of the supercell size
(Elsevier B.V., 2020)
Scandium fluoride (ScF3) belongs to a class of negative thermal expansion (NTE) materials. It shows a strong lattice contraction up to about 1000 K switching to expansion at higher temperatures. Here the NTE effect in ScF3 ...
Influence of Nb-doping on the local structure and thermoelectric properties of transparent TiO2:Nb thin films
(Elsevier Ltd, 2020)
Transparent n-type niobium-doped titanium dioxide thin films (TiO2:1.5 at.%Nb) with pronounced thermoelectric properties were produced from a composite Ti:Nb target by reactive magnetron sputtering. The thin films were ...
Recent progress in high-pressure X-ray absorption spectroscopy studies at the ODE beamline
(Taylor and Francis Ltd., 2020)
High pressure energy-dispersive X-ray absorption spectroscopy is a valuable structural technique, especially, when combined with a nano-polycrystalline diamond anvil cell. Here we present recent results obtained using the ...
