Summary Closely correlating with {200} plane of cubic phase, {103} plane of hexagonal phase of Ge 2 Sb 2 Te 5 plays a crucial role in achieving fast phase change process as well as formation of modulation structures, dislocations and twins in Ge 2 Sb 2 Te 5 . The behaviors of {103} plane of hexagonal phase render the phase‐change memory process as a nanoscale shape memory.
