MAGNETOOPTICS OF (Ga, In) As QUANTUM WELLS : EXCITON BINDING ENERGIES AND CARRIER EFFECTIVE MASSES
Résumé
Transmission measurements, in magnetic fields of up to 16T, have been performed on a series of undoped (Ga,In)As-InP quantum wells. Transitions with Landau indices up to l=15 and energies up to 400meV above Eg are seen. A fit of the experimental data to a theoretical model for excitons at high magnetic fields in very anisotropic systems allows us to deduce values for the carrier effective masses, the electron non-parabolicity and the exciton binding energy.
