The growing demand for physically motivated continuum theories of plasticity has led to an increased effort on dislocation based field descriptions. Only recently rigorous techniques have been developed by T. Hochrainer for performing meaningful averages over systems of moving, curved dislocations, ...
Though usually not considered to be Nanotechnology, modern structural metallic materials are in fact always Nanotechnology. The properties of such common construction materials as steel and aluminium are controlled by their microstructure. The microstructure comprises the spatial arrangement of indi...
There are several textbooks and monographs on dislocations and the mechanical and physical properties of metals, but most of them discuss the topics in terms of more or less one-dimensional or scalar quantities. However, actual metallic materials are often three-dimensionally heterogeneous in their ...

Lichtemittierende Dioden (LEDs) auf Basis des Materialsystems (In)AlGaN, die im ultravioletten (UV) Spektralbereich abstrahlen, werden unter anderem in der medizinischen Phototherapie, beim Pflanzenwachstum oder zur Desinfektion eingesetzt. Mit kurzwelligem UVC-Licht lassen sich auch Mikroben wie Vi...
To enable the fabrication of high performance ultraviolet (UV) light-emitting diodes (LEDs) this work aims at improving the quality of AlN base layers on sapphire substrates. The main issues for UV LEDs are still a limited internal quantum efficiency due to a high amount of threading dislocations al...
This tenth volume in the series covering the latest results in the field includes abstracts of papers which appeared between the publication of Annual Retrospective IX (Volume 265) and the end of May 2008 (journal availability permitting). As well as the 452 metals abstracts, the issue includes – ...
