Abstract:
Within this "Sonderforschungsbereich" we are performing linear Raman spectroscopical and femtosecond time-resolved measurements on quantum dots embeded in glass matrices and thin films, quantum dots and quantum wires located on surfaces as well as on quantum islands in collaboration with other projects located in the Physics Department. The optical properties of such low dimensional systems are of great interest in semiconductor physics. Quantum wires or dots are quasi one- or zero-dimensional systems in which free carriers and lattice vibrations (phonons) show special quantization effects. The energy of the phonons and their dependence on the size of the microstructures in a nanometer range can be determined by linear Raman spectroscopy. The femtosecond time-resolved investigations yield information about dynamical processes taking place after optical excitation.

Key words:
