Abstract
The properties of surface generated electron-hole plasma in Silicon are studied using luminescence spectroscopy. By detailed line shape analysis we determine plasma densities up to 2 · 1019cm-3 for 300K and (ns-)pulse energies of 0.08 J/cm2. We demonstrate that drift effects are essential for the description of the luminescence. Typical plasma drift velocities are about 4 · 106cm/s.
