Deutsche Forschungsgemeinschaft (DFG) - Project number 12387132
The Research Training Group deals with the combination of semiconductors with normal metals, superconductors and ferromagnets. It aims at hybrid systems with novel functionalities that are not feasable with semiconductors or metals alone. Examples are EMR (extraordinary magnetoresistance)-sensors or superconducting Josephson field-effect transistors. To understand and describe the physical and technological properties of the hybrid systems, new methods and efficient algorithms will be developed for the simulation of real systems. The current focus lies on the calculation and simulation of the electronic transport and the motion of the domain walls in ferromagnetic nanostructures on semiconductors. The anisotropic magnetoresistance, the dynamics of the domain wall motion, the vortex and antivortex rotations, as well as the current-induced deformation and movement of walls are studied, for example, by Hall micromagnetometry and magnetic-force microscopy. Some measurements are carried out with the X-ray transmission microscope XM-1 (beamline 6.1.2) and the scanning transmission X-ray microscope (beamline 11.0.2) at the Advanced Light Source in Berkeley.
Further, the Research Training Group focusses on optical investigations on metal-semiconductor microdisks and metal-semiconductor microrolls. The research programme is complemented by an appropriate study programme. The Research Training Group is organised as a Graduate Class of the research focus solid-state and nanostructure physics within the present Department of Physics of the University of Hamburg and involves the Department of Informatics of the University of Hamburg. It is intended to serve as model and contribution to a Graduate School of the Faculty for Mathematics, Informatics and Natural Sciences. In September 2007 the International Summer School "Physics of Functional Micro- and Nanostructures" (www.physnet.uni-hamburg.de/iss/index.html), which is organised by the Graduiertenkolleg and funded by the DAAD programme "Deutsche Sommerakademie", take place in Hamburg for the first time.
