抄録

Ge₂Sb₂Te₅ has been used in DVD disk memory devices where phase transition phenomena between amorphous (glassy) and crystalline state has been utilized reflecting its optics characteristics in laser illumination. In this study, Ge₂Sb₂Te₅ amorphous glassy film was firstly synthesized on glass substrate by a magnetron sputtering device and, then, crystallization kinetics from the amorphous state to crystalline state was investigated during heating treatment using a DSC (differential scanning calorimetry) and its behavior was studied by the Kissinger kinetics. The effect of Nb, Mo and W addition to Ge₂Sb ₂Te₅ during its crystallization has been also investigated for improved performance.
