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 ...
Low-temperature luminescence of ScF3 single crystals under excitation by VUV synchrotron radiation
(American Institute of Physics, 2020)
Photoluminescence and excitation spectra of ScF3 single crystals have been measured under vacuum ultraviolet excitations utilizing undulator synchrotron radiation from 1.5 GeV storage ring of MAX IV synchrotron. The emission ...
