  • Abstract
    We have studied the photoluminescence (PL) of AlGaAs/InGaAs/GaAs pHEMT heterostructures with donor-acceptor doping of AlGaAs barriers. We have found out that the application of additional p+doped AlGaAs layers leads to the appearance of the new bands in the PL spectra. These bands are identified as the transitions between 1) donor-acceptor pairs in the doped AlGaAs layers and 2) conduction subband - acceptor levels in the undoped InGaAs well.
