Abstract :
The effects of metallic precipitation in undoped InP on its lifetime and luminescence have been studied in samples with a gradually increasing concentration of metallic precipitates. It was found that the nonequilibrium carrier decay in this material occurs on picosecond time scale and is of a qualitatively different shape than in materials where deep level traps act as the main recombination centres.
