Abstract

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.

摘要

与立方相的{200}平面密切相关，Ge(2)Sb(2)Te(5)六方相的{103}平面在实现快速相变过程以及Ge(2)Sb(2)Te(5)中调制结构、位错和孪晶的形成方面起着关键作用。六方相{103}平面的行为使相变存储过程成为一种纳米级形状记忆。
