Wissenschaftlich-Technische Berichte FZR – 427 2005 Annual Report 2004 Institute of Ion Beam Physics and Materials Research Editors: J. von Borany, V. Heera, M. Helm, H.-U. Jäger, W. Möller Cover Picture: The front figure shows a schematic sketch of a Si-based microcavity light-emitting diode. The infrared light (λ ≈ 1100 nm) is generated at the boron doped p+n-junction of the diode. The emission characteristics is determined by the cavity formed by the bottom mirror (CoSi2) and the top Bragg mirror (stack of Si/SiO2 layers). For details see contribution at page 9.

It combines basic research and application- oriented studies in the fields of ion beam applications to materials and semiconductor research, with more than 100 scientists, engineers, technicians, and PhD and diploma students. The institute operates a national and international ion beam center, which, in addition to its own scientific activities, offers services and transfers know-how on ion beam techniques to universities, other research institutes, and industry. It is involved in the scientific exploitation of the new experimental facilities at
