The 2D average interparticle distance versus the magnetic field for the exciton, and the singlet and triplet states of the charged exciton in a quantum well of width 100 Å. |
|
|
The 2D pair correlation function versus the magnetic field for the exciton and the spin-singlet and spin-triplet states of a charged exciton in a 100 Å wide quantum well. |
|
|
Comparison between the experimental and theoretical transition energies for charged excitons and excitons in a 300 Å wide quantum well. The open symbols are the experimental results for B > 8 T shifted by 0.5 meV. |
|
|
Comparison between the experimental and the theoretical transition energies for charged excitons and excitons in a 100 Å wide quantum well. For clarity, (a) the low magnetic field region and (b) the high magnetic field region are shown separately. | The symbols are the experimental results.

|
|
The binding energy of a charged exciton in a 100 Å wide quantum well calculated using the symmetric hole mass approximation (thick curves) and the asymmetric hole mass approximation (thin curves). |
