Abstract
The effect of a strong magnetic field on the binding energy and the photon energy dependence of the photoionization cross-section as a function of the well size is studied in a GaAs/Ga1-xAlxAs quantum well for several values of the magnetic field, taking into account the finite character of the barr ier potential. The results we have obtained show that the applied strong ma gnetic field affects drastically the binding energy and the photoionization cross-section and this effect is more significant in a quasi-two-dimension al structure than in a three-dimensional system.
