“…I n [5,61 it was shown that the two-light-source method in PC measurements can be used to separate the contributions of the different impurity levels to the total PC spectrum. Such investigations have already been performed for GaAs: Cr [7] and the advantages and limitations of the method were discussed in detail in that paper.…”

The spatial distribution of luminescence intensity for edge emission and extrinsic Si related bands is studied for Si‐doped LEC grown GaAs crystals. Free carrier distribution is determined from the halfwidth and peak position of intrinsic luminescence and from the position of coupled LO‐phonon–plasmon modes in Raman spectra. An increase of the luminescence intensity with carrier concentration is observed up to n ≈ 1018 cm−3, the sharp decrease for higher concentrations is ascribed to Auger recombination. The temperature dependence of three Si‐related luminescence bands at 1.35 eV (A), 1.2 eV (B), and 1.0 eV (C) is measured. The similarity of the temperature behaviour of the A band with EL2 centres supports its assignment to (Si–AsGa) donors.
