摘要：

We consider the ground and excited states of D- centers, i.e., neutral donors D0 trapping an extra electron, in the spin-singlet and spin-triplet states in GaAs/Ga1-xAlxAs quantum wells (QW's) in quantizing magnetic fields B > 6 T. Taking into account the effects of band nonparabolicity and magnetopolaron corrections, we derive the energies of the dipole-allowed transitions and their line strengths. Very good agreement (e.g., within 1-3 cm-1 below the region of the resonant magnetopolaron splittings) with the experimental data of Huant et al. for the singlet transitions is found.
