Abstract
We report on spatially resolved luminescence measurements on ribbon-grown silicon samples. It is found that the band-edge luminescence shows anomalous temperature behavior, namely an increase in the radiation intensity with temperature. Phosphorous diffusion gettering is found to enhance this effect. The anomalous temperature behavior is attributed to nonradiative recombination governed by shallow traps. A shift in the phonon replica of the band edge luminescence peak has been observed and associated with tensile stress.
