STRUCTURE OF Ge2Sb2Te5 THIN FILMS NEAR THE INFLECTION POINT OF THE RESISTIVITY TEMPERATURE DEPENDENCE
Source abstract
Abstract
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 °C) of the temperature dependence of resistivity and at the end of the crystallization process (183 °С) 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.
