在含有氮NP 1017 cm−3和碳CP 1016 cm−3的磷化镓中,在T=7 K时观察到2087.12 cm−1的尖锐局部振动模式。结果表明,负责这种本地振动模式的复杂的是碳-氮复合物,碳-氮键是一个三键沿沿着001轴的晶格。提出了配合物的微观结构。这表明等价的复合物存在于GaAs中,并以T=7 K时2088.50 cm−1的局域振动模式为特征。这些配合物中的碳原子对晶体的碳p型掺杂没有贡献。
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.
