摘要：

We investigated Ge2Sb2Te5 thin films annealed at the temperatures specific to the crystallization process using transmission electron microscopy. The annealing temperatures typical for the inflection point (168 degrees C) of the temperature dependence of resistivity and at the end of the crystallization process (183 degrees C) were chosen for the TEM studies. These studies clearly showed that the inflection point on the temperature dependence of resistivity is identified with a two-stage character of Ge2Sb2Te5 thin films crystallization.
