Abstract

We report three photoluminescent lines in the 1.504-1.507 eV range in GaAs, associated with excitons bound to defect pairs. The lines are all split by crystal field interaction introduced by uniaxial stress. The highest energy line is strongly polarized in the [110] direction. The polarization selection rules are relaxed by an applied magnetic field clearly demonstrating the crystal field splitting. (C) 1997 Published by Elsevier Science Ltd.
