Abstract
Microwave-induced impact ionization of excitons and shallow donors is studied in Er- and Yb-doped InP. The experimental results indicate a high efficiency of free-electron-related Auger recombination. Yb and Er intrashell emissions are deactivated due to an energy transfer to either free or bound carriers. A new Auger-type nonradiative process is suggested in which the rare-earth-related photoluminescence decays via an energy transfer to a free carrier which has become localized via a short-range potential.Keywords
