In gallium phosphide containing nitrogen NP 1017 cm−3 and carbon CP 1016 cm−3 a sharp local vibrational mode at 2087.12 cm−1 at T=7 K is observed. It is shown that the complex responsible for this local vibrational mode is a carbon–nitrogen complex; the carbon–nitrogen bond is a triple bond aligned along the 001 axes of the lattice. A microscopic structure of the complex is proposed. It is suggested that the equivalent complex exists in GaAs and is characterized by a local vibrational mode at 2088.50 cm−1 at T=7 K. The carbon atoms involved in these complexes do not contribute to the carbon p-type doping of the crystals.
