Photoluminescence spectral evolution from 2DEG-free hole to charged excitons in modulation-doped GaAs/AlGaAs quantum wells

We report on a detailed study of the photoluminescence (PL) in high quality GaAs/AlGaAs quantum wells containing a two‐dimensional electron gas. The 2DEG density was varied by optical depletion (with He–Ne laser illumination) in the range of n2D = (7–3) × 1010 cm−2. The n2D‐dependent PL spectra were...
