摘要
The electron gas confined in GaAs/AlxGa1-xAs quantum wells delta-doped in the barriers has been self-consistently studied in an effective-mass model. In agreement with experimental evidence, our calculations show how the limitations in 2D electron density found in modulation-doped structures can be overcome with the delta-doping technique. The role of different structural parameters of these systems in the practical outcome is also discussed.
