摘要：
The substitutional oxygen defect in GaAs has been investigated with magnetic circular dichroism of the absorption, optically detected electron paramagnetic resonance, and optically detected electron-nuclear double resonance (ODENDOR). The ODENDOR spectra can be explained with an oxygen atom occupying an As site displaced from a regular lattice position along a [100] direction. The superhyperfine interactions and spin densities for several As and Ga neighbors have been determined. The experiments support a model in which the oxygen atom is bonded to two Ga atoms and which shows similarities to the A center in silicon. [S0163-1829(97)03339-0].
