Abstract
We have investigated the influence of phosphorous implantation and annealing on the photoluminescence spectra of Si. The implantation was carried out at 750 keV with doses between 1 × 1013 and 2 × 1014 cm−2. We show that the band edge luminescence of the implantation modified layer at room temperature is low compared to the luminescence from the substrate. The photoluminescence spectra at 80 K are found to depend strongly on the annealing treatment performed (rapid thermal versus furnace annealing). For high implantation doses, a shift in the two-phonon-assisted line is observed and associated with a strong strain field. The band edge luminescence does not show quenching, but increases upon increase of temperature for the highest implantation dose.
