Abstract:The effect of 6.6 MeV proton bombardment and subsequent annealing on the luminescence of Zn, Te‐doped p‐type GaAs crystals is studied and analysed. It is shown that: a) the proton bombardment leads to an appearance of the extrinsic emission band peaked at hvm ≈ 1.26 eV and to a marked decrease in the intensity of the near intrinsic (peaked at hvm ≈ 1.5 eV) emission band; b) subsequent annealing of proton‐bombarded crystals leads, firstly, to a disappearance of the 1.26 eV emission band, and, secondly, to the a… Show more
