Negatively charged excitons in a back-gated undoped heterostructure

説明
The observation of negatively charged excitons in a back‐gated undoped GaAs/AlGaAs quantum well is reported in magnetic fields depending on the electron density between 1 × 109 – 2 × 1011 cm−2. We find that a peak appears 0.3 meV below the singlet charged exciton state at 5 T, which develops to the lowest Landau‐level with increase in the electron density.
