The most attractive application of chalcogenide materials is phase-change random access memory, also called phase-change memory (PCM) [2-3].
However, so far, the phase transitions in such bi-layers PCM stacks has not been systematically investigated, which is critical in understanding the mechanism of improved materials properties.
