    We report photoluminescence (PL) measurements carried out on the 2D A+ center system, that was prepared in GaAs/AlGaAs quantum wells by means of doping wells and barriers with beryllium. In general, four PL lines were observed in our samples depending on doping concentration, temperature and...
