Abstract

The emission spectra of the electron-hole plasma created at the surface of a Si sample by intense laser pulses (65 ns or 400 ps) are investigated. It is shown that the plasma drift is necessary for a consistent interpretation of the luminescence line shape and the energetic position of the line. We determine average densities up to 2.1019 cm−3 for 300K and typical drift velocities up to 4.106 cm/s.

12 The unstructured luminescence bands (see Fig.2) are the sum of TO, LO and TA phonon replica of the transition. To take into account the finite lifetime of the final states we use a formula proposed by Landsberg, which leads to a broadening at the low energy side of the emission line [10].Google Scholar
