Phase Transition of GeSbTe Thin Films Induced by Thermal Treatment and Laser Irradiation Jing Chen1, Fei Yang1, Ling Xu1, a, Liang Tong1, Jun Xu1, Weining Su2, Yao Yu2, Zhongyuan Ma1 1National Laboratory of Solid State Microstructures and Jiangsu Provincial Key Laboratory of Photonic and Electronic Materials Sciences and Technology, School of Electronic Science and Engineering, Nanjing University, Nanjing 210093, People’s Republic of China 2National Laboratory of Solid State Microstructures and School of Physics, Nanjing University, Nanjing 210093, People’s Republic of China a xuling@nju.edu.cn Keywords: Ge1Sb2Te4; phase change; annealing; laser irradiation; crystallization; AFM; Raman Abstract.
Annealing treatment was found to induce changes in microstructure, surface roughness, grain size and so on, indicating that with the increase of annealing temperature, the amorphous state of GST materials change first to face-centered-cubic (fcc) phase state and finally to the stable hexagonal(hex) state.
Introduction Chalcogenide phase-change materials, which refer to alloys containing at least one element of group VI [1], has gained considerable interest as a potential candidate for next decade nonvolatile memory [2,3], are widely used for data storage media.
Si wafer was used as the substrate material.
