The reflected light intensity (I_R) from the solid and liquid phases of Ge-Sb-Te alloy has been statically measured, I_R rapidly decreased after crossing the melting point during the heating process, and increased to its initial intensity level after solidifying during the cooling process. A special sample preparation technique using a quartz cell enabled reliable measurements to be carried out. The structure and composition of the Ge-Sb-Te alloy was investigated using Raman scattering and X-ray fluorescence after the melting process. Germanium was found to preferentially diffuse from the bulk to the surface leading to a germanium oxide surface phase.
