Abstract
Infrared magneto-optical absorption spectra of shallow donor impurity states in GaAs/GaAsAl quantum dot are investigated theoretically using the effective-mass approximation within the strong confinement regime . The numerical results show that for high magnetic fields, the transi tion energies for (0, 0) --> (0, 1) increase linearly with enhancement of magnetic field strength, while the transition energies for (0, 0) --> (0, -1) appear to diminish with increasing magnetic field strength .
