|Abstract:||The radiative recombination of quasi-two-dimensional electrons with photoexcited holes bound to acceptors is investigated in modulation-doped GaAs/AlxGa1-xAs heterojunctions. With increase in temperature, a blue shift of about 2.5 meV is observed for a temperature change from 4 K to 40 K. Also, observed is a rapid decrease in intensity of its low energy peaks. This change in line shape of the acceptor-related emission in the GaAs/AlxGa1-xAs heterojunctions is accounted for by the effect of band bending and the spatial distribution of acceptors. © World Scientific Publishing Company.|
