Abstract
We present a theoretical study of the electron effective mass in Ga1−yInyNxAs1−x∕GaAs quantum well (QW) structures. The calculations are based on a 10×10 k∙p band anticrossing Hamiltonian, incorporating valence, conduction, and nitrogen-induced bands. The results are tested by comparison with the experimentally determined electron effective mass in QWs with indium composition in the range between 10% and 50%, and nitrogen concentration between 1% and 5%. We report good agreement with experiment, confirming that the enhanced electron effective mass observed in the Ga1−yInyNxAs1−x QW structures considered can be fully accounted for using the band anticrossing model.
