Rekristallisationskinetik von Phasenwechselmedien
Phase change media are tellurium based covalently bonded alloys which exist in a meta-stable amorphous phase at room temperature. Contrary to silicon based semiconductors these materials exhibit a large property contrast between the amorphous and crystalline phase. This is employed for optical and …

Strukturelle und kinetische Aspekte der kombinatorischen Materialsynthese am Beispiel der Phasenwechselmedien
Nowadays different competing techniques for reversible storage of huge amounts of data are used. One approach that has found extensive application is phase change recording, whereby data are encoded by using amorphous or crystalline states. Consequently the reading, writing and erasure of …

Simulative Analyse zum Hystereseverhalten von Phasenwechselmedien in Latentwärmespeichern anhand des thermischen Leistungsverlaufs
Latent heat storages based on phase change materials (PCM) are able to store thermal energy almost isothermally, i.e. in a narrow temperature interval. This enables efficient use of low-exergy heat sources with low temperature levels. By using the solid-liquid phase change for energy storage, …

Chalkogenidlegierungen für optische und elektronische Speichermedien
Phasechange alloys are commonly used in optical data storage. Within the next few years an additional application of these alloys is expected to be in solid state memories. In contrast to their widespread use, an understanding of the underlying mechnisms is still incomplete. In this work the …

Stresses, viscous flow and crystallization kinetics in thin films of amorphous chalcogenides used for optical data storage
Modern computers usually contain several kinds of data storage devices. Very frequently magnetic and optical storage media are being used. The latter have become of great interest especially throughout the last decade: nowadays a significant amount of data is being stored on compact discs (CDs) and …
