New Materials Science Data Have Been Reported by Researchers at Australian National University (Reversibility and Stability of ZnO-Sb2Te3 Nanocomposite Films for Phase Change Memory Applications)

By a News Reporter-Staff News Editor at Journal of Technology -- A new study on Materials Science is now available. According to news reporting originating from Canberra, Australia, by VerticalNews correspondents, research stated, "(ZnO)(x)(Sb2Te3)(1-x) materials with different ZnO contents have been systemically studied with an aim of finding the most suitable composition for phase change memory applications. It was found that ZnO-doping could improve thermal stability and electrical behavior of Sb2Te3 film."

Our news editors obtained a quote from the research from Australian National University, "Sb2Te3-rich nanocrystals, surrounded by ZnO-rich amorphous phases, were observed in annealed ZnO-doped Sb2Te3 composite films, and the segregated domains exhibited a relatively uniform distribution. The ZnO-doped Sb2Te3 composite films, especially with 5.2 at% ZnO concentration were found to have higher crystallization temperature, higher crystalline resistance, and faster crystallization speed in comparison with Ge2Sb2Te5. A reversible repetitive optical switching behavior can be observed in (ZnO)(5.2)(Sb2Te3)(94.8), confirming that the ZnO doping is responsible for a fast switching and the compound is stable with cycling."

According to the news editors, the research concluded: "Therefore, it is promising for the applications in phase change memory devices."
