AbstractObtaining information about crystallization kinetics is crucial to understand the transformation speed of phase-change materials and select materials for phase-change memory. In the current work, we first investigated the temperature dependence of the resistance of undoped and In-doped Sb4Te films and found that the crystallization temperature (T-p) and 10-year data retention of Sb4Te increased significantly when it was doped with In. We further employed ultrafast differential scanning calorimetry to explore the crystallization kinetics of In-doped Sb4Te with various compositions, and found In-20(Sb4Te)(80) to have has the fastest crystallization rate (similar to 7.1 m s(-1) at 726.2 K). The In-20(Sb4Te)(80) film exhibited a high Tp (similar to 503 K), better data retention ability (similar to 418.7 K for 10 years), and ultrafast crystallization with strong non-Arrhenius behavior. These results indicated In-20(Sb4Te)(80) to be a promising candidate for use in applications of phase change materials.
