Abstract
The results of interband magneto-optical measurements of GaAs quantum wells are compared with the calculated transition energies and amplitudes in a six-band envelope function approach. The evaluation of the transition matrix elements helps to explain all the essential features of the observed spectra and elucidate the complex effects of hole subbands mixing. Excitonic corrections are included in a simplified manner while a 11% larger value of the electron effective mass is needed to fit the experimental data.File in questo prodotto:
