Temperature dependence of structural and optical properties of GeSbTe alloy thin films

Description

Ge2Sb2Te5 films sandwiched by ZnS-SiO2 layers were studied by spectroscopic ellipsometry from room temperature up to 800 deg. C. An irreversible modification of both materials is pointed out. ZnS cubic phase precipitation occurs after heating at 650 deg. C, shown by grazing incidence X-ray diffraction. Chemical modification in phase change material is observed above 300 deg. C, revealed by a typical behavior of a transparent layer
