Zhakypov, Alibek; Maksimova, Suyumbika; Prikhodko, Oleg; Ismailova, Guzal; Turmanova, Kundyz; Tolepov, Zhandos (The 8th International Conference on Nanomaterials and Advanced Energy Storage Systems; Nazarbayev University; National Laboratory Astana; Institute of Batteries, 2020-08)

Thin films of Ge-Sb-Te (GST) chalcogenide semiconductor materials and, in particular, Ge2Sb2Te5 composition, are used for creation of optical information carrier on the basis of a “glass-crystal” reversed phase transition. ...
Effect of Ag impurity on the optical properties of GST225 thin films

Turmanova, Kundyz; Prikhodko, Oleg; Ismailova, Guzal; Zhakypov, Alibek; Maksimova, Suyumbika; Tolepov, Zhandos (The 8th International Conference on Nanomaterials and Advanced Energy Storage Systems; Nazarbayev University; National Laboratory Astana; Institute of Batteries, 2020-08)

Intensive research is currently underway to develop materials for the optical recording of information based on a glass-crystal phase transition. Promising materials for this direction are thin films of chalcogenide ...
