Abstract
We studied structure and dynamics in liquid Ge and . Quasielastic neutron scattering (QNS) was employed to accurately determine the Ge self-diffusion coefficient. Static structure factors were measured using neutron and x-ray diffraction. Containerless processing via electromagnetic levitation (EML) enabled to obtain structure factors over a broad temperature range from the metastable regime of the undercooled melt to several hundred Kelvin above the melting point. Moreover, isotopic substitution and combination with x-ray diffraction allowed to determine the partial structure factors , and for liquid . The topological structures of liquid Ge and are very similar. In addition, the Ge self-diffusion coefficients in liquid Ge and are equal within error limits.
