E24: Experimental Semiconductor Physics I (Gerhard Abstreiter)

Research projects of E24 deal with various aspects of electronic and optical properties of low-dimensional, mesoscopic semiconductor structures, the heteroepitaxy of group IV and III-V semiconductors, the development of novel methods for lateral patterning and self assembly of quantum wires and quantum dots, the use of various analytical tools for the characterization of nanometer-sized structures in collaboration with external groups, as well as the fabrication and test of new, unconventional electronic and optoelectronic devices. Examples for basic research are optical spectroscopy of single quantum dots, cleaved edge overgrowth on GaAs, magnetotransport in ultrahigh mobility GaAs heterostructures as well as electronic transport and tunneling in edge channels and one-dimensional systems. Device and technology oriented work aims at novel concepts for charge and spin storage in quantum dots, coherent devices based on quantum dots for future quantum information technology, photonic crystal microcavities for efficient single photon sources and the test of semiconductor nanostructures for chemical/biological sensors. A new area of research is the controlled manipulation of oligonucleotides on gold surface for possible protein detection and the development of SOI based lab-on-a-chip systems. Also of increasing interest are carbon based nanostructures and combinations with organic molecules.
