RF spectra of the free and excitons under magnetic fields increasing from 0 to 10 T taken at 4.2 K. and resonances are associated with lower- and higher-energy polariton branches.
PL spectra of the free and bound (lines 2, 4, and 5) excitons under magnetic fields from 0 to 10 T taken at 4.2 K. and resonances are associated with lower- and higher-energy polariton branches.
The evolution of the spectral positions of the free , , and excitons under the influence of magnetic fields in the RF (symbols and ◼) and PL (symbols ◻ and ○) spectra. The solid lines are quadratic functions least-square fitted into the experimental values of the diamagnetic shifts.
