摘要

Neutron diffraction measurements of the liquid Ge–Te system and quasi- and inelastic neutron scattering experiments of the eutectic liquid Ge15Te85 were performed in the temperature range from 400 to 560 °C. The large temperature dependence of the static structure for liquid Ge15Te85 is reconfirmed; however it is found that the compositional dependence obtained at around 80 °C above the liquidus curve is rather small. The dynamic structure factors of liquid Ge15Te85 in the Q-region from 0.2 to 2.6 A-1 show a normal temperature dependence. From the vibrational density of states, it is found that the Te–Te covalent bond persists in liquid Ge15Te85; however a bending mode was not assigned clearly.
