10. Terahertz spectroscopy of zero- and two-dimensional semiconductor nanostructures with the free-electron laser FELBE
Dr Harald Schneider (Helmholtz-Zentrum Dresden-Rossendorf)
The free-electron laser facility FELBE in Dresden, a unique source of intense, quasi-cw, nearly transform-limited ps pulses in the mid-infrared and terahertz (THz) regimes, provides unique research opportunities. In high-quality semiconductor quantum wells, we investigate the dynamics of excitons, i.e. two-dimensional, hydrogen-like electron-hole quasi-atoms. Tuning FELBE in resonance with the...

Free electron lasers (FEL) are unique X-ray sources regarding pulse duration, coherence properties and peak brilliance. Their potential to study ultrafast dynamics has been demonstrated in time-resolved x-ray spectroscopy experiments. Time-resolved photoelectron spectroscopy (TR-PES) is a very valuable tool to study non-equilibrium electron dynamics of condensed matter systems. However, due...
Dr Paul Beaud (Paul Scherrer Institut)
The exploration of the subtle interaction of structural and electronic degrees of freedom in strongly correlated electron systems on the femtosecond time scale is an emerging area of research. One goal of these studies is to advance our understanding of the underlying correlations, another is to find ways to control on an ultrafast time scale the technological relevant properties of these...
