• Carbon in semi-insulating gallium arsenide (GaAs) crystals has been investigated by Fourier-transform IR absorption spectroscopy, spark source mass spectrometry, and charged particle activation analysis. Procedures for the quantitative evaluation of the 582-cm^<-1> local mode absorption due to carbon on the arsenic sublattice (C_<As>) are described. The strength of the mode shows a linear correlation with total carbon content measured by spark source mass spectrometry over the concentration range from 3×10^<14> to 2×10^<16> cm^<-3>. The new calibration factor for the integrated absorption at 77 K is (7.2±0.4)×10^<15> cm^<-1>, based on a relative sensitivity coefficient of 3.2±0.1 of the spark source mass spectrometry. Calibration factors for thc IR absorption method at room temperature are also given.
