Research Abstract

Undercooled liquid state of metals and semiconductors can be observed when the cooling of those molten states. One of the origin of anomalous properties of undercooled liquids might be related to the large fluctuation in liquids, which is derived from the nucleation or the embryo of solid state. In this study, we observed the atomic dynamics in undercooled liquid metals by using the electrostatic levitator and the high resolution inelastic x-ray scattering technique together with the synchrotron radiation facility.
