Abstract
Spatially resolved photoluminescence (PL) and electron-beam-induced cu rrent (EBIC) measurements were performed on a heat-treated SIGMA = 25 silicon bicrystal at 4.2 and 300 K. The early stages of both profiles across the grain boundary (GB) obtained for PL and EBIC scans were int erpreted in terms involving the existence of a denuded zone on either side of the GB. Otherwise, a dissociation mechanism, due to GB precipi tates, of the condensed and free excitons is evidenced and has led to the determination of the spatial distribution of these particles.
