摘要: The substitutional oxygen defect in GaAs has been investigated with magnetic circular dichroism of the absorption, optically detected electron paramagnetic resonance, and electron-nuclear double resonance (ODENDOR). ODENDOR spectra can be explained an atom occupying As site displaced from a regular lattice position along $〈100〉$ direction. superhyperfine interactions spin densities for several Ga neighbors have determined. experiments support model which is bonded to two atoms shows similarities $A$ center silicon.
