Luminescence Spectroscopy on Highly Excited Si - Experimental Determination of the Plasma Drift Velocity
Published online by Cambridge University Press: 22 February 2011
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.
