    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.
