Paper Abstract

The exciton binding energy have been calculated as function of the magnetic field and the quantum well width for the various exciton and magnetic states. The variational calculation carried out in the adiabatic approach has shown the sizeable enhancement of the exciton binding energy with increase of the external field. For rather strong magnetic fields the exciton binding energy has been found in a framework of the perturbation theory. The results were used for the analysis of the spectra of light transmission through the thin semiconductor film containing GaAs/Al0.3Ga0.7As multiple quantum well structures and InxGa1-xAs/GaAs strained multiple quantum well structures in the external magnetic field tuning from 0 to 7.5 T at T equals 2 K.
