Optical studies of GaAs:C grown at low temperature and of localized vibrations in normal GaAs:C
… the integrated optical absorption of the carbon localized-vibrational-mode band. At higher dopings, the LVM integrated absorption saturates. Formation of C<sub>As</sub>-C<sub>As</sub> clusters is proposed as the mechanism of the saturation. The photoluminescence spectra were successfully analyzed …

Optical studies of highly-doped GaAs:C
… at that p. Secondary-ion mass spectroscopy and localized-vibrational-mode measurements indicate that the Hall-effect-derived hole concentration is close to the carbon concentration and that the Hall factor is close to unity, so that the Hall mobility provides a good estimate of the actual dc …
