FIG. 1.

The electronic structure and density distributions of samples from self-consistent calculations.

FIG. 2.

(a) PL spectra from 0 to 7 T (1 T step) for sample 1 . (b) Landau fan diagram for the P3 transition.

Image of FIG. 3.
FIG. 3.

(a) PL spectra for sample 1 in pulsed magnetic fields to 45 T. (b) The transition energies for P1, P2, and the GaAs FX as a function of magnetic field. The straight broken line below 6 T for P1 is guide for the eye. Up and down arrows indicate which shrinks in magnetic fields above 10 T.

Image of FIG. 4.
FIG. 4.

(a) PL spectra in pulsed magnetic fields to 30 T (1 T steps) for sample 2 . (b) The transition energies for P1, P2, and the GaAs FX as a function of magnetic field. The straight broken line below 7 T for P1 is a guide for the eye.
