本文报道了一种典型相变材料Ge2Sb2Te5液相结构的x射线吸收研究。我们证明了液态Ge2Sb2Te5的局部结构与非晶态Ge2Sb2Te5非常相似。发现液相中的Ge原子是共价键，表明熔体具有半导体性质。
We report on x-ray absorption studies of the structure of the liquid phase of a prototypical phase-change material Ge2Sb2Te5. We demonstrate that the local structure of liquid Ge2Sb2Te5 is very similar to that of amorphous Ge2Sb2Te5. Ge atoms in the liquid phase are found to be covalently bonded suggesting a semiconducting nature of the melt.
