摘要：
The crystallization kinetics of thermally deposited Ge2Sb2Te5 (GST) films has been investigated using temperature-dependent sheet resistance (R-s) measurements in combination with structural investigations employing x-ray diffraction (XRD). By Kissinger plot, the activation energy for crystallization is determined to be 1.87eV. The sheet resistance of the GST samples decreases from 0.7M Omega/square to 153 Omega/square upon annealing above the phase transition temperature and the crystallization temperature (TC) was found to increase with heating rate (beta).
