Auger Effect Seen in the Porous Silicon Fast Luminescent Band
Published online by Cambridge University Press: 09 August 2011
Abstract
Time resolved photoluminescence (PL) measurements are performed on oxidized and fresh porous silicon at room temperature. Comparing the evolution of the nanosecond time delayed PL in both cases, a new feature of the PL spectra is identified: the fast-red band, present as well in fresh or aged samples. The nonlinear excitation intensity dependence of this component is described by a simple model where, the Auger effect inside isolated silicon nanocrystallites plays the dominant role.

For a maximum pulse energy of about 10mJ/cm2 one has 2.1016 cm−2 photons which will be absorbed in the porous layer, in a proportion of (1−exp(−αl)) ≅ 0.8 (e.g. for the fresh layer). Taking an average density of the silicon crystallites of about 1018 cm−3, one obtains an average number of excited e
−−h pair/crystallite of ≅200. This corresponds to the highesi excitation intensity, meaning that in our experiment the average number of e
−−h pairs excited inside a crystallite during the laser pulse, is scanned from 1 to 200.Google Scholar
