Crystallization kinetics in antimony and tellurium alloys used for phase change recording
… Most frequently, magnetic and optical storage media are used. The latter have become of great importance throughout the last decade: nowadays a significant amount of data is stored on compact discs (CDs) and digital versatile discs (DVDs). A few years ago, rewritable CDs and DVDs have become …

Application of p electron theory to predict new materials for rewritable optical recording
Phase change recording is based upon the reversible phase transformation of a chalcogenide Te alloy between the crystalline and amorphous states using a focused laser. The formation of the micron-sized bit of information is distinguished from the difference in the optical properties of the two …

Development of nanofocusing refractive X-ray lenses
… of structural transformations in thin films of phase change media and the investigation of residual stress in aluminium mirrors were made. In future, fluorescence tomography experiments with a resolution in the range of 100 nm are feasible. •To fabricate nanofocusing x-ray lenses made of boron, …

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 …

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 …
