PROF. DR. ANDREAS WIECK, CHAIR FOR APPLIED SOLID STATE PHYSICS

Andreas Wieck is the director of the Institute of Experimental Physics and professor in the Department for Physics and Astronomy at RUB, holding since 1993 the Chair of Applied Solid State Physics. He performs Molecular Beam Epitaxy in ultra-high vacuum of IIIV-compounds as AlxGa1-xAs and InyGa1-yAs with thicknesses of sub-atomic layers up to 10µm, using band-gap engineering and dopants as Si and C to create on 3”-wafers High-Electron-Mobility-Transistors, Quantum Wells and Quantum Dots to produce light emitting diodes, laser diodes, transistors and single photon sources for quantum informatics and cryptography. He pioneered Focused Ion Beams for mask-less doping and sputtering. Andreas obtained his PhD with experiments at the High-Field Magnet Laboratory in Grenoble/France at the University of Hamburg, was 8 years tenure researcher at the Max-Planck-Institute for Sol-id-State-Research/Stuttgart and 1 year at the NTT Basic Research Labs in Tokyo/Japan before joining RUB.
