The single layer Zn44Sb39Se17 thin film, being fabricated by Sb70Se30 and Zn using co-sputtering method, exhibits double phase change transition. The double phase change processes are mainly attributed to the crystallization of the Sb and ZnSb phases. The potential operating temperature for ten years of two phase change processes are 64 degrees C and 179 degrees C, of which the good stability of the second phase change can be sufficient for the autoelectronic applications. Meanwhile we also discovered the Zn44Sb39Se17 thin film presents apparent low power consumption in comparison with Ge2Sb2Te5 and other reported Sb-Se based phase change materials.
