The kinetics of the radiative recombination of 2D electrons with photoexcited holes, localized in a monolayer of acceptors at a given distance from the interface, has been studied at a single GaAs/AlGaAs heterojunction. The time scales for the recombination of the 2D electrons from the ground and excited quantum-well subbands have been determined for various distances between the 2D channel and the monolayer of acceptors.
