Paper Abstract

We studied the lifetimes and the luminescence spectra of photoexcited carriers in H+ bombarded InP and GaAs for different damage doses by means of femtosecond luminescence spectroscopy. For InP the lifetime decreases down to 95 fs for the highest dose, whereas for GaAs no shorter lifetime than 650 fs could be observed. With decreasing lifetime we observe an increase of the high energy tail of the time-integrated luminescence spectrum which is even inverted for the 95 fs InP sample.
