A Reversible Change of Reflected Light Intensity between Molten and Solidified Ge–Sb–Te Alloy
スポンサーリンク
概要
- 論文の詳細を見る
The reflected light intensity ($I_{\text{R}}$) from the solid and liquid phases of Ge–Sb–Te alloy has been statically measured. $I_{\text{R}}$ 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.
