    • Abstract

       

      The experimental data on the Hall measurements have been used to characterize deep electron trapping levels in Cr doped semi-insulating GaAs crystals. The energy of the level below the conduction band edge has been found to be ∼ 0·8 eV and is thought to be related to Ga vacancies in the host crystal and Cr impurities.
