Coulomb Energies

Positive trions in a quasi-two-dimensional hole gas confined in symmetric and asymmetric GaAs quantum wells are studied by a combination of polarization-resolved photoluminescence and transport measurements in high magnetic fields B (up to 23 T) and low temperatures (down to 30 mK). The experiments are accompanied by realistic numerical calculations. The whole family of trions (the singlet and a pair of triplets) are observed. The singlet-triplet crossing of Coulomb energies is found: hidden in symmetric and visible in asymmetric structures.
