摘要
In this paper we discuss some major aspects on the physics of the phase transition from the amorphous to the face-centered-cubic (fcc) polycrystal in Ge2Sb2Te5 at low temperature. We follow the phase transformation by using structural techniques such as TEM, XRD. and electrical resistivity measurements by using the 4-point-probe technique. The results are interpreted in the framework of a quantitative model. (C) 2009 Elsevier B.V. All rights reserved.
