Abstract

The structure of liquid Ge15Te85 has been studied with neutron diffraction in the liquid state up to 740 °C and in the supercooled liquid state down to 345 °C. The temperature dependences of the diffraction patterns are analyzed. It is shown that the liquid Ge15Te85 can be described by the model of heterogeneous structure, which assumes that the melt consists of atoms joined in clusters and a proportion of atoms with higher mobility that fill the space in between clusters. The number and the size of clusters decrease while the volume fraction of 'free' atoms increases under heating.
