Crystallization kinetics of phase change materials for novel data storage concepts
After a general definition of phase change materials and a description of their defining properties, such as the possibility to switch between two room temperature stable phases at high speed and a contrast in optical and electrical properties, the history of phase change research is shortly …

Optische Eigenschaften von Phasenwechselmaterialien für zukünftige optische und elektronische Speicheranwendungen
Phase Change Materials offer a unique combination of physical properties, thus they yield successful applications. They are used in re-writable optical data storage and will be in the near future also used in electrical data storage. The alloys, employed up to now in optical data storage are …

Electronic switching in phase-change materials
Phase-change materials (PCM) possess a unique property contrast between their crystalline and amorphous phases. Differences in resistivity of some orders of magnitude can be observed between both phases. Also, the reflectivity shows a remarkable contrast, and it allows the application of thin …

Development and application of a massively parallel KKR Green function method for large scale systems
… to hundred thousand processors. The quantitative change of atoms treatable from first-principles translates into qualitative new physics as it becomes now feasible to investigate the properties of defects, alloys and the electronic properties of disordered systems in general. Thereby, the …

Electrical transport and switching in phase change materials
Phase change materials, typically composed out of Ge, Sb and Te alloys, are materials that can switch very fast between two stable states, the amorphous and the crystalline phase. The optical contrast of the two stable phases led to the application in optical data storage such as compact disks …
