摘要
The fine structure in the 0.61-eV photoluminescence band from the deep defect EL2 in semi-insulating GaAs has been studied under uniaxial stress and magnetic field. The results show no deviation from full T(d) symmetry and hence support the isolated-arsenic-antisite model of EL2. Measurements of both the shift due to the hydrostatic component of the stress as well as the g factor of the final state of the transition confirm the identification of this photoluminescence with EL2.
