摘要
Infrared absorption due to the localized vibrational modes of Si and Be has been investigated in low temperature molecular beam epitaxial GaAs. A spectrum from Si(Ga)-V(Ga) has been found, but pairing of Be(Ga) was not detected. Anneals of the Si doped layers led to Si-site switching and an apparent loss of silicon from solution. A comparison is made with a previous study of neutron irradiated Si doped GaAs.
