Abstract

Semi-insulating and SI-doped <100> GaAs have been irradiated to a dose of 1016 protons cm−2. Samples have been annealed for 20 minutes at 400,500 and 600°C. Cross-sectional TEN has shown the as-implanted and 400°C annealed GaAs to contain no visible damage. After 500 and 600°C anneals a heterogeneous distribution of planar raft-like defects apears on {(11} and {110}. The density of these defects is much lower in the Si-doped material.
